    A monoatomic gas of n-moles is heated from temperature T1 to T2 under two different conditions (i) at constant volume and (ii) at constant pressure. The change in internal energy of the gas is                                                [CPMT 2000]

    A)            More for (i)                          

    B)            More for (ii)

    C)            Same in both cases           

    D)            Independent of number of moles

    Correct Answer: C

    Solution :

                       Change in internal energy \[\Delta U=\mu \,{{C}_{V}}\Delta T\] it doesn?t depend upon type of process. Actually it is a state function
