    A gas in a container is compressed suddenly. Its temperature would

    A)  increase

    B)  decrease

    C)  stay constant

    D)  charge depending upon surrounding temp.

    Correct Answer: A

    Solution :

    As compression is sudden, changes are adiabatic. \[dQ=0\] As \[dQ=dU+dW=0,\]therefore \[dU=-dW\] In compression, dW is negative, therefore, dU is positive, hence Internal energy would increase. Therefore, temperature of gas must increase. Hence, the correction option is [a].
