    A thermally insulated vessel contains an ideal gas of molecular mass MM and ratio of specific heats 1.4. Vessel is moving with speed vv and is suddenly brought to rest. Assuming no heat is lost to the surroundings and the vessel, the temperature of the gas increases by : (R=(R = universal gas constant ))
