1 kg air in a piston-cylinder assembly is heated at constant pressure, resulting the expansion of the volume. The initial temperature of the air was 300 K, and the air temperature becomes 500 K after the expansion. What is the boundary work done by the air? Assume that air is an ideal gas with constant specific heats ( 0.718 v c = kJ/kg-K and 1.005 p c = kJ/kg-K)..
