Question 1: Thermodynamics & KTG

Question

The zeroth law of thermodynamics for three systems $A, B$ and $C$ in contact demands that

Accepted Answer

According to the
Zeroth Law of Thermodynamics
,
If two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
Let us apply this to the systems $ A $, $ B $, and $ C $.
Suppose $ A $ is in thermal equilibrium with $ B $.
Suppose $ B $ is in thermal equilibrium with $ C $.
Then, according to the Zeroth Law, it follows that
$ A 	ext{ is in thermal equilibrium with } C. $
Hence, all three systemsÃ¢ÂÂ$ A $, $ B $, and $ C $Ã¢ÂÂare at the
same temperature
.
Therefore, the correct option is:
Option D:
$ A, B 	ext{ and } C 	ext{ are in thermal equilibrium.} $
