Question

A rigid tank whose volume is 4 m3, initially containing air at 1 bar, 295 k, is connected by a valve to a large vessel holding air at 6 bar, 295 k. the valve is opened only as long as required to fill the tank with air to a pressure of 6 bar and a temperature of 320 k. assuming the ideal gas model for the air, determine the heat transfer between the tank contents and the surroundings, in kj.
