    The volume of a gas increases by a factor of 2 while the pressure decreases by a factor of 3. Given that the number of moles is unaffected, the factor by which the temperature changes is:

    A) \[\frac{3}{2}\]             

    B) \[3\times 2\]

    C) \[\frac{2}{3}\]             

    D) \[\frac{1}{2}\times 3\]

    Correct Answer: C

    Solution :
