Two bodies P and Q, are in thermal equilibrium, which of the following statements about the bodies is correct?
- the temperature of Q is higher than that of P
- P and Q have the same heat capacty
- P and Q have the same mass
-
P and Q are at the same temperature
The correct answer is: D
Explanation
When two bodies are in thermal equilibrium, it means that they have the same temperature. This is because, in thermal equilibrium, there is no net transfer of heat between the bodies, indicating that they have reached the same temperature.
