Solution

The correct option is C gas
Internal energy is dependent on the freedom of movement of particles. Since in gaseous state, particles are most free to move, this state has maximum internal energy.

In the P-Vdiagram show, moles of a gas are taken through a process from state i to f, at constant pressure. Part of the heat must have gone into doing the work $P Δ V$ , and the rest in increasing the internal energy. If the molar specific heat at constant volume for the gas is $C_{V}$ , and the initial total internal energy is $U_{i}$ , what is the final internal energy $U_{f}$ ?
