A well insulated rigid container of volume 1m3 contains 1.0kg of an ideal gas [Cp = 1000 J/(kg.K) and Cv = 800J/(kg.K) at a pressure of 105 Pa. A stirrer is rotated at constant rpm in the container for 1000 rotations and the applied torque is 100 N-m. The final temperature of the gas (in K) is____________?
