Ironically I had sat down to watch this with a cup of tea that I had brewed a little while ago. Scientific me started to think back to her college days of taking chemistry and learning about the behavior of different molecules, wondering what is really going on inside the tea kettle with hard water in it and what the minerals do to the temperature of the water. Another part of me came into my head and said, "Oh, just enjoy the hot tea and stop it!"

yup... amazed again. as I scrolled through the videos cherry picking the ones with interesting titles, always going past this and afew other videos until they were the only ones left. my thought process here was there was going to be a bar graph like decline from most interesting at the top to boring being at the bottom. flawed lol all were just as interesting as the next and last. Much respect and love from Canada 🇨🇦 for this enlightening adventure StarTalk! looking forward to future. \m/-.-' PS I love how subliminal these titles translate to everyone's experiences for school when they were younger. uninteresting titles. none enthusiastic room filled with fresh minds. but you convey very easily that never judge before you know what your judging. and also... the setting in school and being put on the spot in front of the class was too much for me to handle so I just never went to classes where that was a common thing. anxiety can really hold back some youngsters from their true desire for a higher learning. if it were one on one or a teacher and like 5 others.

Water remains at 100°c when boiling starts, and then stays at the same temp, because phase change takes the energy, also called latent heat of fusion. When water is completely boiled, and steam is given energy further more, its Superheated steam. Thanks for the information Neil, I remembered it while watching.

[@MisterIncog]

There is some interesting things about boiling Neil didn’t mention. Water ALWAYS converts into gas (well, any liquid, but let’s stick to the water). The thing is, molecules of water have different energy, different speed they vibrate, so to speak. The molecules at the edge between water and gas (air) with high energy eventually detach from liquid water structure and become gas water molecules, or steam. That’s why you can dry wet clothes in the cold weather. So, how is boiling different? Remember those bubbles that form when you boil water? These are steam bubbles, of course. The molecules of water get so much energy in every part of your pot, steam can form inside water. Neil told a little lie in the vid, water does have molecular structure, it’s just not as organized as ice’s. And even that structure breaks with high enough energy of individual molecules, and that’s why steam is forming inside water.

[@guytheincognito4186]

It's a little white lie in a sense but still true in the sense he ment it as it not having a rigid structure. This is because the small hydrogen bonds only holds it together for a fraction of a second. Hence, (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. Water molecules are constantly on the move.

[@MisterIncog]

@@guytheincognito4186 yes, of course. I just pointed it out because it was needed for further explanation

[@guytheincognito4186]

@@MisterIncog (Edit.Typo.) No problem. I only pointed out this bit myself to alleviate the issue of having someone misconstrue and or confuse the meaning of "lie" as it's used here. It might be an overreaction on my part but there are people that will jump on the tiniest possible incongruency in order to attack an persons standing or ideas plainly for the sake of it. In the past I wouldn't even react to it but today you almost expect a flash mob to instantaneously appear wherever the term lie appears even tangentially with anything scientific. 😅🤣🤣✌

Another interesting tidbit about "boiling water"... The boiling point of water decreases about 1ºF per 500-ft of elevation gain above sea level. The sea level boiling point is 212ºF, but up at 7,500-ft where I live in Colorado, it's about 198ºF.

Amazing, loved it as always BUT it does rather leave me wondering, what is the next part of the experiment? By that I mean, if you keep increasing the temperature of steam does it have its own version of boiling? Or can you increase the temperature indefinitely?

[@MisterIncog]

It turns into plasma eventually. Well, if you have enough energy to convey

[@shakthiweerawansa5548]

Well practically speaking the steam can only get as high as the temperature of the flame itself which is about 3500°F

The orange tank used to be white on first few missions of the Space Shuttle, but the weight and cost of painting the tank white was too much, so they stopped.. I work in health care kitchens, and had another guy argue me that the food pans need to sit in the water, because it is hotter... the tables to hold food are called steam tables.. so means steam is what you are using to keep the food hot, so you want the water level under the pan.. so steam is heating the food.. the roof the roof!!! LOL this was a very entertaining and educating explainer!! I never knew about why toast takes forever to show and browning, but then goes so quickly!! but learned something knew and will remember this one!

[@gnarthdarkanen7464]

The MAIN concern with a steam table is that you have sufficient water to cover the heating elements (if so equipped, which most are)... If it's aboard ship, the steam tables are heated with super-heated steam through pipes... Let those get dry and you start wearing them out... AND you do NOT want one of those to spout a pin-hole!!! Super-heated steam (modern day at about 2000F) can't be seen. It's "dry" steam, but you tend o find it with a wooden dowel by waving the thing around the "hissing" pipe until the end is sliced off... Wherever that happens is where there's a pin-hole... ;o)

A master class in cooking fundamentals.

[@xdragon2k]

And this is why cooking in oil, barbecuing, and steaming has different effect on the food above the fire. The temperature that the food is bathing in is different with different method.

[@gnarthdarkanen7464]

There's also a different "carrier chemical" involved in reacting with and delivering different "extractives" to and from the food (and spices count as part of the food) depending... A LOT of the most popular flavors and aromatics are actually more organically solvent, rather than readily water-soluble, meaning you need an "oil" or carbon-based carrier... SO fats and oils actually carry and help the spices in question deliver more of their flavors into the other foods... In some cases, too much heat causes "thermal decomposition" in the desired extractives, so you have to keep the temperatures lower, and it takes much longer for the food (meat often) to be rendered "safe for consumption"... This is the case in smoking and curing, where salt is (frequently) a major constituent of both flavor and cooking (chemically)... SO a smoker might only ever reach between 185 and 210 F, to give the oils and water enough time to move through and over and out of the meat in the process of cooking... Further, anyone with sufficient experience with a slow-smoker process, will generally stock poultry at the bottom, beef in the middle and fatty pork at the top of the smoker, to allow the higher fat contents carry down from the pork over everything else, and the lighter flavor of the chicken dry out and soak up the flavors cascaded down in that time. It's delicious and efficient... even if it takes hours to "do the magic"... ;o)

Several years ago, as an adult, I did the thing where you watch the temperature while boiling water. I was just messing around because I didn't write it down. But I made the same observation. Temperature stopped increaseing at about 212F / 100C.

[@societyispatheticdeathisma8233]

So if you had a pressurized water tank on a steam engine in a low pressure environment or vacuume. And you had a valve to open the tank would a steam engine run without the need of heating the water? You could just open the valve and go?

[@bullettube9863]

Understanding steam was one of the great scientific fields that allowed the industrial revolution to take place. Steam power is not an archaic science, nuclear powered ships and power plants use the incredible power of steam to generate electrical power and propulsion. Fun fact: keeping the cooing fluid in a car under pressure makes it more efficient at keeping engines cool. The normal pressure in a car engine is 20 psi at 220 degrees (F) maintained by the engines' thermostat. Which is why you do not open your radiator cap without standing back, otherwise you get scalded!

[@boilingsnowwater2121]

Aw yeah that's the stuff.

[@STNeish]

I once pondered what would happen if you increased the temperature of water, but kept it contained in an infinitely durable area. That is, imagine you have an indestructible force field that forces the water molecules to remain within that space, no matter how hot they get. What would happen if you just kept adding heat? The liquid would eventually turn to steam and fill the space. However, as the temperature continued getting higher, the steam molecules would accelerate their movement... but the field would prevent them spreading out any further. What would happen? If you kept adding more energy, more heat, what would happen? Would the molecules themselves break up? Would the atoms themselves come apart?

[@Ryuk-apples]

The temperature would definitely go higher than 100C because the pressure is strong keeping it liquid even though its over 100C. The reason it does boil at 100C with no additional pressure is because the standard pressure is equal to 1 atmosphere.

[@STNeish]

@@Ryuk-apples Ya, that's what I thought... the pressure would increase on and on... but is there a point of no return? Is there a point where the molecules couldn't gain any more energy?

[@OfficialRost]

@@STNeish there is a temperature at which molecules break up into atoms and then plasma. If you keep adding energy to it you would then break the atoms up into constituents like quarks and electrons, but we’re already at energies higher than the ones in the sun

[@gnarthdarkanen7464]

@@STNeish I've forgotten the exact temperature/pressure requisite, though I'm sure you could research it through wikipedia and bibliographic references or a scroogle search... BUT... There's already been a state of "common matter" discovered at incredibly high temp's and pressures only reachable in recent technology... It's called "Super critical" and it's in the super-critical state that water shows two remarkable new features... First, it acts like a metallic substance and Second, it becomes a more universal solvent... It's pretty incredible stuff... Not sure how much farther someone could "push" the theoretical limits of energy into materials like water, but as Official Rost points out, at least in theory, there's a point where matter begins to break down to fundamental particles and waves... BUT we're not really sure past the super-critical and plasma forms of matter... We haven't been able (yet) to get "there" with the stuff... In any case, there's a few new terms you can search and explore if you care... Enjoy and "good hunting"... ;o)

Hi guys, I enjoy all your shows, otherwise I wouldn't watch them all. On boiling water: you left out 3 things you might want to add next one: . In 1) boiling water at altitude , it boils at lower temlerarure 2) Adding a salt lowers the boiling point 3) boiling water with ice ! Fill a sealable air tight flash 1/4 with water . Seal it, and cool it in an ice bath. This lowest the vapor pressure in the fast to the point that the water Will boil ! -_- perhaps one could power a rocket, in the vacuum of outer space, by releasing water in a rocket nozzle . However water is a scarce and valuable commodity in space!. Did you guess I am a Chem. Eng .

[@petejohnson8397]

interesting thing about fire rated drywall.... as it is heated water is released and turns to steam. which prevents the drywall from getting hotter than 100c until all the water has been released, preventing the fire from spreading to the other side for a period of time
