Question

The Bat Life: What can be said with 100% confidence about the temperatures at point $P_{1}and{P}_2$?

• A. $T_{P_1}=T_{P_2}$
• B. $T_{P_1}$ > $T_{P_2}$
• C. $T_{P_1}$ < $T_{P_2}$
• D. $T_{P_1}\ne T_{P_2}$.

Answer 1

The correct option is D

$T_{P_1}\ne T_{P_2}$.

Just like a single macroscopic pressure being undefined for a gas which is not in equilibrium, a single macroscopic temperature is also undefined. So the temperature at $P_{1}and{P}_2$ need not necessarily be the same, and most likely wouldn't be the same.
