    An ideal gas is initially at a temperature T and volume K Its volume is increased by \[\Delta V\]due to an increase in temperature \[\Delta T,\]pressure remains constant. The quantity \[\delta =\frac{\Delta V}{V\Delta T}\] varies with temperature as

    A)

    B)

    C)

    D)

    Correct Answer: C

    Solution :

    [c]  \[V\propto T\] \[V=CT\] \[\frac{dV}{dT}=C\]                \[\delta =\frac{1}{V}\frac{dV}{dT}=\frac{C}{CT}=\frac{1}{T}\] \[\delta \propto \frac{1}{T}\]
