At constant pressure P the volume of a gas increases from V1 to V2 when 'Q' amount of heat is removed from the system. What will happen to internal energy?

MCQs on thermal equilibrium, zeroth law of thermodynamics, heat, internal energy and work, thermodynamics first and second law, thermodynamic processes, heat engines, heat pumps and refrigerators, carnot engine, thermodynamics specific heat capacity, reversible and irreversible processes.
