A gas is kept in a container having walls which are thermally non-conducting. Initially the gas has a volume of $\displaystyle 800 \mathrm{~cm}^3$ and temperature $\displaystyle 27^{\circ} \mathrm{C}$. The change in temperature when the gas is adiabatically compressed to $\displaystyle 200 \mathrm{~cm}^3$ is: (Take $\displaystyle \gamma=1.5 ; \gamma$ is the ratio of specific heats at constant pressure and at constant volume)
