In order to explore how the entropy (s) of a gas depends on temperature, volume, and pressure, evaluates the state of 1 kg of nitrogen at 100 kPa, 300 K using the IG state daemon. Now holding mass and volume constant (hint: Vol2 = Vol1 in state-2), evaluate a series of states at different temperatures. Plot how entropy (s) changes with temperature. In a similar manner, plot how entropy (s) changes with temperature when pressure is held constant.
