State and briefly explain the meaning of the four laws of thermodynamics (zeroth, first, second and third?

Answer 1

0th law: No thermal energy is exchanged between systems of identical temperatures. Or, more formally, if A is in thermal equilibrium with B, and B is in thermal equilibrium with C, then A is in thermal equilibrium with C.

As for the main three laws, the best explanation I've heard goes as follows:

1. You can't win. (Energy is neither created nor destroyed, formally dU1=-dU2)

2. You can't break even. (For any macroscopic process, mechanical energy is always lost due to increase in entropy, formally ds>0)

3. You can't get out of the game. (IF one could carry out processes at absolute zero, it would be possible to lose no energy to entropy, but unfortunately, absolute zero is unattainable. Formally T>0)

Answer 2

In a really oversimplified summary...0th law defines temperature...1st law is just a statement of conservation of energy....2nd law is basically just a physics way of saying something like "if I have 100 pennies and flip them all at random they aren't very likely to come up all heads"...3rd law says you can't achieve absolute zero

Answer 3

frequently, people who make that declare have faith that the 2d regulation could be reformulated to tutor that complicated ordered structures can't upward push up with the aid of organic strategies. If that have been real we does no longer have hurricanes. in actuality, the creationist declare is in accordance with a pretend impression of the thought-approximately entropy. they think of that using fact it is colloquially defined as being reminiscent of "disease," that each and all and sundry styles of disease are entropy and all entropy is disease.
