Why Does Altitude Affect Temperature? |James May's Q&A | Earth Science

[@dimii_music]

My geography teacher showed this video to the class, and when I saw that James may was presenting it. Being the top gear watcher that I am It simply made my day

[@amelsfr]

I wish he was still doing this... he's great! and with the perfect voice!

[@mightymaniac8712]

I think James May is peculiarely entertaining

[@razaqk8047]

SAME

[@l.lawliet1551]

this was the question i had for a very very long time actually glad it helped

[@TheKRIVI]

That voice, I could listen to his voice all day.

[@bingooslo]

The air temp stopps falling in the Tropopause about 30.000 fet at the poles and 56.000 fet at the equator and the temperature increases in the stratosphere.

[@RandomThought301]

I have a few questions. How does a touch screen work? How are multi-layered Blu-ray discs made? How do cell phones transmit voice? I'm also really interested in any Physics based knowledge you can bestow. Thank you sir.

[@bachirontzki7087]

I will admit that science and knowledge are the only reasons I'm subscribed to this channel. However it having a charismatic and intelligent presenter that I just happen to have seen before on another show I enjoy watching, is a nice bonus, as are all the other wonderful presenters, editors, misc crew this channel has.

[@lesconrads]

These are so well produced and nicely informative. No shake-cam.

[@Rethic]

James May, i will admit... is the only reason i'm subscribed to this channel, watch the videos and like the videos i watch.

"where it's 04:20 in the morning" snoop lion confirmed for next top gear guest star

[@MrRullakebu]

TY! HAVE BEEN WAITING, sry caps too exited

[@amyyyyy24]

The cabin is pressurized to around the same pressure you would find at ~10,000ft. If a plane is at cruising altitude, the pressure outside will be much lower than the pressure inside the plane, and since areas of high pressure naturally go towards areas of low pressure, you get sucked out of the airplane.

[@gabrielpoquet3725]

4.20.... in the morning huehuehue

[@noney81]

huehue

[@davidbillython185]

sneaky shout out to all the boize

[@soumya.himself]

That’s called sprite bro

[@adrilol8702]

THATS WHAT I THOUGHT LMFAO

the ending is pretty chilly this time, well done

[@Heirofscotland]

James just waiting for this Sunday! Top Gear

[@been01010]

that acctually help's quite a bit, thanks

[@kasuha]

The funny and counterintuitive part of the whole thing is that the atmosphere is the cooler the higher you go because it is getting cooled (by escaping infrared radiation) from above. If it was completely isolated, it would have the same temperature at any height despite varying pressure.

[@IvarMarthinusen]

Do you have any references to this video. I have always been under the impression that hot air rising is not a closed system, and therefore PV=nRT would not be valid. I have always been under the impression that hot air rising into an area of less pressure will be able to hold less moisture, and as this water condenses it takes heat away from air.

[@jfolck1886]

I am only subscribed to this channel because I saw James in a video a couple months ago. I thought it was his own channel. As for the subscribe thing, maybe throw it at the end, not in the middle. Say something like "if you liked this video be sure to subscribe so you can see when we upload new ones" or something like that.

[@jamesdunn3864]

Sorry to be pedantic James but, just to remind myself as much as anyone else of that really useful information one learns as a pilot, the International Standard Atmosphere provides for a standard temperature/pressure of 15 degrees C/1013.2 millibars at sea level, a temperature drop of 2 degrees C per 1000 feet until the start of the troposphere at 36,000' and thereafter a constant temperature of about -57 degrees C. Of course, since these are only standard values, the real values on any day can differ from these standard values. If you're flying in a non-pressurised aircraft in a really hot climate, say in the Middle East, you can't wait to get up to at least 5,000 feet since that's where you start to notice a useful drop in temperature. Conversely, however, when you're descending to land at an airfield at sea level, you should expect to have to change your shirt after landing...

[@matchbox2022]

+James Dunn And why is that Mr. Pilot. I'm sure he'll make an ozone layer video eventually....It's just a general now you know video not a degree in atmospheric science.

[@unamaxify]

even a great entertainer & explainer like James May needs people who do the video editing, animations, research etc, So it would be nice if those people would get some recognition too

[@1224chrisng]

actually I find the "your journey" page quite useful

[@Cloxxki]

Take an ampty coke bottle, screw it shut. Kick down on it as it lays on the ground. Bouncy? That's an air spring. Now make a small hole in the cap. Ideal would be an airbed valve or sort, with a smaller opening leaving air out than in. Repeat the kick down test. Less impact on your foot, less bouncyness. That's how shock absorbers work. The "bottleneck" (or a soft matress like elastomer) converts impulse to heat as it can't be transerred or sprung back immediately.

[@SquashBox]

Also, if you get exposed to the high temperatures above the mesosphere, you wouldn't feel anything because the molecules of atmosphere are so far apart they do not interact with your skin. When we feel the hot sun warming our cheeks it's because the atmosphere around our cheeks was energized by the sun and is now interacting with our cheek.

[@lakejindsay]

Here's a slightly interesting twist. 80° F at sea level versus 80° F at 5000 ft of altitude might feel the same but the sun's rays are more harsh at altitude. Their impact on skin cancer and just general burning is more pronounced at altitude. This may seem obvious but some people say that it feels hotter at altitude when the temperature is high. But it's just the impact of the sun's rays that they are feeling.

[@McLamborghini]

They do, but it has to be solar. The only other way that I can think of to use heat like this as a power source would be Steam. But that also requires gravity to help create the oscillation of motion. Steam up, gravity/water down.

[@JagoBridgland]

thank you, james, for this information

[@Talon3000]

"Gently" is the key word here. An annotation at the beginning or at the end of the video would suffice.

[@Shiimochi]

James May is awesome.

[@mrwinkie1959]

As you go higher in altitude the force of gravity which is holding the atmosphere to the planet gets weaker locally because the gravitational force is more spread out. Because the force of gravity gets weaker with altitude the atmosphere isn't held to the planet as strongly and this is why atmospheric pressure gets weaker with altitude.

[@albertboyles7637]

Can you try to make a video to explain atmospheric carbon and its thermodynamic relation between its point of origin, or altitude of emission; during its half-life.

[@autobahn2501]

James you are great.

[@benderrodriguez2159]

1:03 It scared the shit out of me when he paused it, i thought he was right behind me.

[@YR2050]

This only applies to water, because solid ice has a higher volume per mass than liquid water. To accommodate the reduce in volume due to extreme pressure, ice turns to water, or what seems to be a raise in melting point. However, all other elements has a higher density in solid state than its liquid state, thus increase pressure for those substances will only low their melting point.

[@Doctormario4600]

Good grammar is frequently associated with high intelligence, but the two don't necessarily *always* go hand in hand (even though they often tend to).

[@gyeosabayo]

this is a serious stuff.,., i love informative videos, especially videos that tells you things that you won't hear at school.,.,

[@Karma8Kami]

So.... if the temperature difference is that big from shade to sunny side in space, why isn't every single space vesel and station using thermo electric generators instead of solar panels? Seems to me the potential energy production would be much higher with those? Now that's one I'd love to see a video on ^^

[@reembtsv5009]

loved this video, love that guy

[@TheFlymar]

About high temperature in space? What about the falcon feather and the hammer experiment. In the video the lunar surface seems to be lighted so I guess it;s a day. Sghouldn't the feather melt or something? It couldn't burn because of lack of the oxygene. Isn't the vacuum a quite good temperature isolator?

[@woomba7]

you'd be amazed how many more people actually subscribe when you gently remind them to on a periodic basis

[@UnderArmourWolf]

pulling is more controllable than pushing.

[@thesecondislander]

Why would the shaded side be cold in space? with so few particles absorbing the heat it wouldn't cool at all right? or maybe you were talking about the upper upper atmosphere

[@BlackSunOfNile]

WOAH thank you !!

[@Raviolishangout]

james may the only reason i subbed because he is from top gear

[@NemanorTheAlmighty]

I love this show

[@clapetto]

3:10 That's wrong. In the last US spacewalk on the ISS one of the astronauts said that it was chilly.

[@Reaper33B]

I have a question for mr. may...how does a nuclear reactor work compared to a nuclear bomb and is uranium the only material that can be used?

[@RoyalError]

I see what you did there when mentioning the subscribe button. Clever.

[@TheRLindsey]

The astronaut's suits were designed with radiation heat in mind. They basically act like miniature environments and insulated the effects from radiation from the astronauts.

[@SzileeMester]

Maybe I missed something, but why does it colder in the mountains if the sunlight is reflected from there too?

[@conned]

Lol, imagine Captain Slow talking about adiabatic lapse rate. Good stuff!

[@kidcraft153]

Here is a question i've always been wondering : If you was shot by a gun that makes you 1/2 of your cuccerent size, smaller every single secound, how long time would it take before you just dissapear?

[@TheDarren2020]

James, why do we instantly forget things right after we do them? (Why after I wash my hair do I forget and then do it twice?)

[@HDH3CZ]

The ending was so deep

[@TheRockhem]

Darnit, on BBC america i have to wait until july 8th for it to premiere (whyyyyyy........)

[@TheKaneDestroyer]

What I want to know, is why the air shoots you off the aeroplane if the windows are open in an aeroplane in the air. Above the clouds.

[@alexhydron]

Here are the things that i watched last night : James May's toy stories James May's my sisters top toys James May james may's things you need to know ( full ) James May's 20th century ( full ) James May on the moon James May's Man Lab ( just one episode i didn't like it that much ) James May's Big Ideas ( full ) and after watching all that in a row i have to say, thank you James May....

Exactly.

[@ceejaybizzle]

I'M ALREADY SUBSCRIBED, DAMN YOU. Another ruddy good video though.

[@forbiddenmonkey7416]

James make a podcast already!! :D

[@rockbore]

I don't see where the minus 180 C comes from. I don't see how a bolt or any bit of metal, for example, could have such a temperature gradient. What about a spinning nut? Does a spinning nut go through temperature changes like that on each revolution? That would be ridiculous. What is the mechanism for this extremely low temperature? Can you replicate it experimentally in a vacuum oven?

[@Tygur]

Due to the Sun heating the surface and the heat radiating back up. A solid surface collects a lot more heat than air.

[@Cerealkillergaming]

I love this

[@daltreyd]

How does electrical energy transfer into other forms of energy such as sound or light

[@Cloxxki]

Should make for a nice heat exchanger powered high-altitude airplane you'd saw. But, how to thust it without an athlosmere? You're stuck bringing ballast up all the way.

[@idiotwn]

Does Cyriak do these animations for Head Squeeze? It looks like his style, minus some of the disturbing stuff.

[@busyman05]

YES!

[@louistimotheebrunner]

isn't the absorption the same if you increase in altitude then why should that make a difference?

[@B0XMATTER]

@RePeakify He is the guy from Top Gear. Smart man that Mr. May. My personal favorite.

[@08megamon]

yes,he is

[@Guy9998]

No it's not laziness. It's usually because they don't know any better. Many people don't seem to realize you're is a contraction just like the same people will write there instead of they're like "there going over there". The funny thing is when you really listen, provided the speaker is speaking correctly, your and you're don't even sound the same. I can't stand when people say of instead of have like "you shouldn't of done that" or "Sean and myself are going to the station".

[@msrina5546]

lapse rate is 1degree Celsius for every 165.65 meters

Of course not. The universe is literally everything, there is nothing beyond the universe because the universe is infinite.

Question: Why do we like and dislike things? and why does the likes and dislikes of people differ?

[@Kayen4]

This time when James asked me to subscribe I felt like he was threatening to murder me so I desperately looked at the subscription button which told me: ''Subscribed''. And before a new breath was drawn, I blew out all of my fear as James turned back into his regular self.

[@Reaper33B]

Already knew the answer to this one. Entertaining nonetheless.

[@TurboTelytJim]

So, if the atmoshpere has a temperature due to the pressure of air molecules, does space have no temperature to speak of?

[@DerekHundik]

but what happens with the air pressure after 38000 meters

[@zedek_]

Air pressure does not get colder or warmer. Air pressure increases or decreases. Air *temperature* gets colder or warmer. Can you please rephrase what it is you're asking exactly?

[@manjilagrg242]

why is thickness of troposphere less in poles ??

[@Doctormario4600]

That's all well and good if you don't mind having your grammar corrected (because English is your second language) but a lot of people don't like it.

[@rovik30]

where does the energy in the hot air that risees go for it to become cold ?

[@mariacassandrataruc2574]

what is the difference between air pressure and atmospheric pressure?

[@sevvenelevven]

The difference between a FART and a HURRICANE..literally..!!

[@Deltaworks23]

Could someone please explain about freezing temperatures in the vacuum of space? Obviously you could feel heat because of radiation. But without an atmosphere to remove heat from my body, would I actually feel a sensation of cold? If I am not mistaken, spacecraft are painted white to reflect back radiation so they don't overheat, but the skin of the lunar module in the Apollo missions was quite thin and the astronauts did not freeze. What am I not getting here?

[@Nemozoli]

Yes, you would feel the cold, because no atmosphere doesn't mean there is no radiation emanating from you. You would radiate out all of your heat in the infrared wavelength faster than getting heated by the Sun's rays, thus freezing to death in a matter of hours. That is, if you were on the outside of a spacecraft... inside the more serious problem is the absorption of heat from the Sun, transferred to the "inner atmosphere" - if our central star is visible. Whilst in the shadows, the spacecraft would emanate heat and get almost nothing in return, losing heat continuously.

[@Deltaworks23]

Ah, this makes sense to me now. Thank you very much for the explanation.

[@Nemozoli]

Deltaworks23 : You're welcome! I just noticed the vast time-gap since your comment, and was wondering if you could read mine at all... :-)

[@भूतपूर्वजैन]

please some one answer this. as we go up, there are less clouds, so there is more direct sunlight. dos this mean that, say at 25,000 feet, there is direct sun on you and at the same time, very less temperature?

[@Chris-fy8rk]

No as there would be around 36.000km of Atmosphere above the clouds which still blocks alot of Radiation
