    Answer is b The internal energy is a state function dependent on temperature. Hence, the internal energy change is zero. An ideal gas by definition has no interactions between particles, no intermolecular forces, so pressre change at constant temperature does not change internal energy. Hence kinetic energy will tend to remain the same. Real gases have intermolecular interactions, attractions between molecules at low pressure and repulsion at high pressure. Their internal energy changes with change in pressure, even if temperature is constant.

    reshav here Del V is change in volume

    eduncle-logo-app

    you know this....pressure volume work done case

    eduncle-logo-app

    so directly if work done here is negative then Del V is also negative
