Re: is there a 'zero'law of thermodynamics

Hi Suzie,

you are right, this "0th Law" exists, but actually it is something you probably don't consider worth thinking about. You have different but equivalent formulations, one of them is:

"The zeroth law of thermodynamics states that if for example you have a Body (A) and a Body (B), both at the same temperature; and then you have a Body (C) which is at the same temperature as Body (B); Therefore the temperature of Body (C) is equal to the temperature of Body (A)."

So, you see, it is quite easy - if A=B and B=C, then A=C! (If you want to be a scientist, you can replace "same temperature" by "thermal equilibrium", but it means esentially the same).

Bye, Andreas
