  • For an ideal gas :

    A
    the change in internal energy in a constant pressure process from temperature `T_1 toT_2` is equal to `nC_v(T_2-T_1),` where `C_v` is the molar specific heat at constant volume and n the number of moles of the gas.
    B
    the change in internal energy of the gas and the work done by the gas are equal in magnitude in an adiabatic process.
    C
    the internal energy does not change in an isothermal process.
    D
    no heat is added or removed in an adiabatic process.
