The Laws of Thermodynamics, Entropy, and Gibbs Free Energy

We've all heard of the Laws of Thermodynamics, but what are they really? What the heck is entropy and what does it mean for the fate of the universe? How does soap work?! So many questions answered in this clip! Enjoy!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

If you would like a more comprehensive explanation of these laws, go to my classical physics playlist! Clips 28-31 cover the four laws, one law per video, and they are much more in depth than what is mentioned here!

I teach both high school physics and chemistry. In the unit of heat, both of these classes overlap quite a bit. It was hard to find a good video explaining the laws of thermodynamics and entropy. I like KHAN, but they are too long. Others are too abstract or goofy. This gets to the point quickly as you speak very clearly and with conciseness. Any high school science student would find these clips good to watch.

This man saved me from failing my high school. I'm graduating with Physics honours next month. Thanks Dave ♡

Dave: There is a layer of math beneath the intuitiveness
Me: *holds breath*
Dave: ..we won't get into the math
oh thank christ

Professor Dave, I always enjoy watch your YouTube videos and admire you for working so hard to educate others. Big Thanks!

Never thought I'd be taught the Laws of Thermodynamics by the Jesus himself, but I'm going to take it

[sashamuller]

at first you might not like the opening but after a couple of professor dave explains videos you'll be singing along no doubt

[angelaelizando]

I will never look at hand soap the same way again. Your videos are all very informative.

Mom: why is ur room so untidy??

Me: it's entropy broo

*slipper flies across room*

I'm a homeschooled sophomore. I watched this in seventh grade and took notes throughout. When it got to the question at the end, I actually got the right answer--without a calculator! It was explained so clearly and with such clever analogies. I'm watching it again just for fun! Thanks so much for this, Professor Dave! It answers a lot of questions for me and helps me understand much more about the way the universe works.

I am in first year of university studying chemical engineering and this video put the complex concepts very simply. Thank you!

[upandatom]

This video was great! You're awesome at explaining the science stuff :)

[redwood]

Im not a college graduate i was in the military but i still find what your saying so fascinating... i want to learn.
Dont give up on me

[lumiwang]

Up to 5 min, I felt that I have learnt more than watching previously 50min of college chemistry teaching videos. Very concise and informative! Thank you!

[carbon]

That was scary






I almost understood entropy😳

[sehmio]

Thank you for explaining things clearly and making it easy to understand! I really appreciate your time and effort Prof!

[patrickj.]

Beautifully explained! Definitely nice when you can understand how all the variables work together. Thanks!

[adammtroutman]

I love Professor Dave now. The man does his homework, and explains things so beautifully clear and concise. Respect

[saraswathii]

The explanation was so good that I could explain all the stuff to my friends clearly

Studied Chemical Engineering a while back and having a bit of a refresher on the basic principles. Really great job in explaining the abstract, which can take so long to understand. Learning 'what' and 'why' is so often conceded in favor of 'how' and 'when'. And yet it can be explained in 5 minutes.
