Laws of Thermodynamics

[MrSilvestris]

This video contains many errors and only describes thermodynamics in closed systems.

[MrSilvestris]

In the Zeroth Law of Thermodynamics which is the law that describes equivalency and not flow; Heat goes in both directions.

0:05 1st law of thermodynamics, ΔU = W + Q

0:12 entropy change, ΔS = Q/T or ΔS = k*ln (Wf/Wi)

0:58 Heat flow, q = -k*Grad T

1:02, Newton's law of cooling, dQ/dt = h*A*ΔT

1:09 Stefan–Boltzmann radiation law, P = A*e*σ*T^4

I ♥ Thermodynamics and physics

[julianpap]

i'm not gonna read all this shit

[MegaCrazydutchman]

@julianpap yes you are

[TheLittleTrickster]

This made me want to watch a musical theatrical play

[bernoullilizard]

What about the zeroth law?

[HumanChemistry101]

Who was in that scale-size Newcomen steam engine background image? (Watt?) What do I have to Google to find the image?

[bfleck]

@HumanChemistry101 Yes, I think it was supposed to be Watt. I held onto the graphics for a while but I don't believe I still have them. Will look today on my other computer.

[HumanChemistry101]

@bfleck Thanks. If you find it, please send it to me for use at Hmolpedia, the biggest thermodynamics encyclopedia on the Internet.

[HumanChemistry101]

@bfleck Also Google "music thermodynamics", and you will find an Hmolpedia article on the history of the use of thermodynamics in song, from Flanders and Swan, to MC Hawking, to David Ng's 2009 song the thermodynamics of love, among others.

thumbs up if you use this to study for your test and in the middle of it you break out in song and dance XD

[jangeds2]

Where I can get this song?

I love it.

[TheAlps36]

Brilliant song, equally brilliant animation.

[bfleck]

@TheAlps36 Thanks. I have been trying to find another similar project. Everybody seems to like the periodic table song but there are so many animations of that song already out there.

I had an Academic Bowl question that asked "What famous Physicist came up with the law that states 'Heat is work'?" I knew it was the first law of Thermodynamics because of this song, but I had NO idea who came up with it. I sang the song in my head trying to see if they mention it, but they don't. When time called, I guess Flanders. (Just because...)

[bfleck]

@2blackbelt031394 So did you go home and look up Clausius? That's one of the pictures that passes by during the video, along with Newton, Fourier, Stefan and Boltzmann.

[HumanChemistry101]

@2blackbelt031394 "What famous Physicist came up with the law that states 'Heat is work'?", the most likely answer they were looking for in that query would be James Joule, in the sense that they were really asking: "who derived the 'mechanical equivalent of heat'?" (+15 more people). You could also argue for Benjamin Thomson (Cannon boring experiment, 1798), or Rudolf Clausius (dU = dQ - dW, 1865) as the correct answer (although technically the question is too vague to be answered correctly).

[bfleck]

Thanks. Had fun making it.

Beautiful job. Love the "cool" Fonz.

[richard8221]

the only reason im watching this is cause of my CHM class.....

[QuadfishTym]

Woah, the first 2 times I watched the part with the match striking I could actually smell it somehow...
