Question: A rigid tank whose volume is 4m3, initially containing air at 1 bar, 295K, is connected by a valve to a large vessel holding air

A rigid tank whose volume is 4m3, initially containing air at 1 bar, 295K, is connected by a valve to a large vessel holding air at 6 bar, 295K. 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 380K. Assuming the ideal gas model for the air, determine the heat transfer between the tank contents and the surroundings, in kl. O2=
