Thermodynamics: What do HEAT and WORK really mean? | Basics of Thermodynamics

[@reemibrahim4847]

The MASTA has just uploaded!!

You admit the truth. None of us understand thermodynamics completely. I have learned lot from your video.

I was having so much trouble understanding this in class, thank you this was so helpful!

[@andragavril9994]

Im having my midterm tomorrow and one of the chapters i have to cover is thermodynamics and Maxwell s ecuations so thank you for your videos. They really help!

[@Ottmar555]

I like this definition of thermodynamic work better (Principles of Thermodynamics, Ansermet & Brechlet, 2019). 1.- For every system, there is a scalar extensive state function called energy (E). When the system is isolated, the energy is conserved. 2.- When the system interacts with its environment, the energy evolution results from the power of the processes exerted on the system. 3.- PW represents the mechanical power associated with the work performed by the environment on the system that results in a deformation of the system without any change in its state of motion, in particular its kinetic energy. I really suggest you this book. I also really like Thermodynamics: Principles and Applications by Ismail Tosun. It's more engineering oriented, but it has great explanations and intuition.

[@nunushetmitiku4481]

Thank you for your hard work during this time. this is the channel what I have been looking for 😍😉

[@ClemoVernandez]

thermodynamics I think has the most conventions which make it difficult to understand even if the phenomenon is really intuitive

[@eduardoschweitzer1152]

I'd love to see a video about the Navier-Stokes equation. Great video btw

Heat : energy transfer we couldn't be bothered to track directly Work : energy transfer, but not heat Edit : one could say that the varibales regarding heat are distributed boltzmannly

[@rockbore]

Two suggestions for vids. 1 Show how the Apollo crew were cold while flying in sunlight. 2 Show how the Radiation belts are not deadly as Dr James van Allen reported following his survey with Explorer 3 3 How probable was the L.O.R. operation to lose no lives after 6 missions.

[@Demonprinz1]

Regarding your first question, thermal energy can transfer by 3 (one could argue about 4 but thats fiddly and minor) major ways. One of them is radiation, which we experience when we sit in broad daylight. The other ways all need a medium to travel. This medium, some atoms kicking each other or vibrating or just moving, is rather rare in space thou which causes a rather poor transfer of thermal energy. Because of the very low pressure in space there is practically only radiation by which heat travels. Sadly radiation is a rather slow way to transfer thermal energy because of which it is not impossible to get cold in space even in full sunlight. Next up, one could argue standing a long time on front of the operating end of a X-Ray isn't deadly either, the cancer you'll win by this kill you, but I doubt this is your topic you want to get to. Van Allen Belt Radiation can be an acceptable risk when the shielding is thick enough. About 10 mm aluminium are capable to shield off most of the radiation and traveling fastly trough the van Allen Belts exposes the crew to a potentially non lethal dose of radiation. This does not mean the radiation is safe in any way, it just means it is possible to deal with it properly. Sadly the way to deal with the radiation increases the weight of a spacecraft quite considerably. Because of this it has gotten really expensive to fly people to the moon again, lowering the safety would be cheaper but is not an option. Actually to be honest your third point seems rather useless to me. The mission happened and they survived. They took risks they thought to be acceptable and came back. In hindsight the safety measures were lacking, of course, but in the times they were up to date. They leaned from previous mistakes, and did what they could to avoid them. If they didn't do that the deaths would have been in vain, and it'd be an insult to their families. Was there still a risk? Of cause. Did literally anyone know that? Of course. Still, now we can measure the distance to the moon by shining a laser at the mirrors they left there whenever we want (only during unclouded nighttimes of course but hey thats kinda obvious).

Great video! Great explanation! Well done! I have got a quick question though: Can free electrons ( not interacting with electromagnetism) or other kind of leptons exist in room temperature?

[@eduardoalcamino4162]

I have an unrelated question, but pls answer: General relativity works great to predict movement of mercury for example, but doesn’t at galaxy level sizes, as there is allot of matter that isn’t taken into account(dark matter), so why don’t they apply a constant that multiplies the formula to contrarest dark matter per unit of space, so at planetary scale it’s close to nothing, but at galaxy level sizes, it multiplies it by nearly 20, so 5% =>100% and then this thing would improve the formula. Pls someone answer, idk if this is just moving a operation that you had to do after, in the formula or not!

[@doinggood3564]

Make video on navier stokes equation...if u can...

[@mikeb2644]

Really great. Clearly defined. And you're very, very easy to watch and listen to. (You remind me of one of my favorite internet science teachers-- Dr Mike of Dr Matt and Dr Mike. In my book, that's a huge compliment.) THE FOLLOWING IS MY QUESTION-------------------- I have a question about the box with the fire under it. The molecules in the box would vibrate, and then the molecules in the air surrounding the box would vibrate-- those things would be the transfer of heat. Right? But the box might also start to shake and move. Would that be work? ********************************************************************************* Thank you again for the great video. I look forward to watching others. (And I also want to thank for the animations. I wish more chemistry videos would use them, since movement is at the heart of so many chemical, biological and physiological phenomena.

[@johansharma4109]

Nice video. One thing.....if there is no atmosphere outside the box i.e. vacuum outside the box then work done by gas is 0

[@xiaoshen194]

I thought you would explain entropy also in detail. (You know, topic like multiplicity, etc.)

[@Demonprinz1]

Nice video to tip the toe into the topic of thermodynamics. I think a follow up video, maybe looking at the ways that heat transfers (radiation, convection, conduction and advection) would be nice. I think it's hard to distinguish between heat and work in the drawings, because it seems like in both cases it's just one particle hitting another. I'd love to see a few more videos to thermodynamics because in my opinion it is quite fascinating but takes a hell lot time to properly understand. And then there are things like S=k_b*ln(W) which just comes out of nothing.... well I know the statistical approach tells that S in Boltzmann's relation works out to be the thermodynamic entropy but its still hard to grasp for me how Boltzmann linked the macroscopic world to the microscopic phase space that "easily".

[@YathishShamaraj]

The explanation was quick and simple love it Bro 👍♥️

[@subita7835]

It would be amazing if you could do some Electromagnetism videos. Videos on topics like faraday and lenz’s laws, Electromagnetic induction and motion of particles in a magnetic field would be really useful as for A-Level Physics they are very conceptually hard!

Given simplified: 2 Samples under an Illuminate "Heat Lamp" one is metal and the other is carpet so "where does the heat go" on the carpet as "violation of energy" nothing just disappears and how is it that metals "absorb" only the specific band is this matched to atoms resonance to that specific frequency then what of say the same 250Watts at near UV then why does the metal heat when only at a specific band? ( serious question / mechanic - physicist by nature )

[@Mona-cj4nt]

I would like to ask about examples in our lives we use heat and work?

[@nathangrant1824]

could you say something about the pressure gradient of a gas in a container subject to the force of gravity? this seems a bit of a vague question and an answer with too much maths is going to go over my head. i was wondering if there would always be a gradient even with very high pressure and heat, even if that gradient was extremely hard to measure or could only be determined by a statistically minded maxwell's demon analysing the motion of the gas at every point of space in the container. thanks for any thoughts you may have and can take the time to share.

[@gunashekharramanathan9224]

Hello parth. Thanks for your videos. Can u please answer my question.. i can't derive it neither i can find the formula anywhere in books or internet. stone is attached at the end of a string. Another end is fixed to a big nail pierced in wall. The stone is given such a motion initially that it now performs veritcal circular motion(velocity at top sqaure root of rg which is the minimum condition for vertical circular motion) What will be the time period of this motion.
