    The temperature of 1 mole of an ideal gas decreased from 324 K to 300 K adiabatically in which amount of work done is 60R. Find heat supplied to the gas in increasing the temperature of the gas from 300 K to 324 K under isochoric process-

    A) 12R                              

    B) 24R

    C) 40R                              

    D) 60R

    Correct Answer: D

    Solution :

    For adiabatic process \[dW\,\,=\,\,-dU\] \[60\,\,R\,\,=\,\,n\,\,\frac{3}{2}\,\,R\,\,\left( 300-324 \right)\] \[n\,\,=\,\,\frac{120}{72}\,\,=\,\,\frac{5}{3}\,\,\]
