Thermo - Zeroth Law

Has anyone run into any questions asking about the Zeroth law of Thermo? I am going through the AAMC topics and it simply says:

Zeroth Law: Concept of Temperature

I am aware that there is a such a thing called temperature, but I am just wondering to what level we are supposed understand this and how it could potentially be tested. I know this is left field, but it is on the "list".

The zeroeth law of thermo is that if one object is in thermo equilibrium with another object, and that 2nd object is in thermo equilibrium with a 3rd object, then objects 1 and 3 are in thermo equilibrium with each other.

So like the commutative property, if A=B, and B=C, then A=C?

Joy!

It's just saying if I have a cold block and a hot block, and i bring them together both blocks will equilibrate to the same temperature. if another block is also in contact with those 2 blocks, it too will be at the equilibrium temp. So yes, basically what you said 🙂

not to nitpick, but i believe you mean the transitive property of equality.

commutative suggests something like,

A + B = C and B + A = C

sorry. its pathological 😳

Nah, thats cool. I would have done the same thing. That is why I asked the question.
