A gas is enclosed in a cylindrical can fitted with a piston. The walls of the can and the piston are adiabatic. The initial pressure , volume and temperture of the gas are `100 kpa, 400cm^(3)` and `300k` respectively. The ratio of the specific heat capacities of the gas is `(C_p / C_v = 1.5)` Find the pressure and the temperature of the gas if it is (a) suddenly compressed (b) slowly compressed to 100 cm^(3).
