Consider 3 kg of air contained in a piston-cylinder system. The air begins at a pressure and temperature of 3 bar and 500 K, respectively. The air is rapidly expanded until it exists at a pressure and temperature of 1 bar and 300 K, respectively. Calculate the change of entropy, in , of the air during this process (Ratr = 0.287-) kg-K 3 kg of air
