    At constant temperature the pressure of a gas is increased to three times, then its volume becomes:

    A) \[\frac{V}{3}\]                  

    B)        \[\frac{2}{3}V\]

    C) \[3\,V\]                               

    D)        none of these

    Correct Answer: A

    Solution :

    Key Idea: According to Boyles law \[P\propto \frac{1}{V}\] at constant temperature \[\therefore \] when pressure increases by 3 \[\therefore \]volume decreases by \[\frac{V}{3}\]
