A gas is kept in a container having walls whic h are thermally non - conducting. Initially the gas has a volume of 800 cm 3 and temperature 27°C. The change in temperature when the gas is adiabatically compressed to 200 cm 3 is : (Take  = 1.5;  is the ratio of specific heats at constant pressure and at constant volume)
