Thermodynamics

How to prove the zeroth law of thermodynamics?

Do your own homework, kid.

I guess you could approach this either experimentally or theoretically.

Experimentally you could go to the lab and perform experiments to determine if 2 systems are in equillibrium with another system they are in equillibrium with each other.


But I enjoy the math, and think it would be more fun to theoretically prove this law.

lol, he edited his post to make it not so blatant.

Isn't the zeroth law if A=B and B=C then A=C? Isn't that an axiom?

Yeah if a=b and b=c then a=c. But I was saying you could go into a lab and perform an experiment. Maybe boil 3 or so pans of water, and get out a thermometer.


But I was saying it would be more fun to prove it theoretically using the 2nd law of thermo and some differential equations or something.
