A closed flask contains water in all its three states: solid, liquid, and vapor at 0°C. In this situation, the average K.E. of the water molecules will be:
Q1. A closed flask contains water in all its three states: solid, liquid, and vapor at 0°C. In this situation, the average K.E. of the water molecules will be:
Answer: The same in all three states
Explanation: At thermal equilibrium (0°C), all three states share the same temperature, so the average kinetic energy of molecules — which depends only on temperature — is identical across solid, liquid, and vapor.
