Argon gas (MW = 40) is compressed in a closed system from 100 kPa and 30°C to 500 kPa and 170°C. For argon, the specific heat at constant pressure (Cp) is 0.520 kJ/kg-K, and the specific heat at constant volume (Cv) is 0.312 kJ/kg-K. What is the specific entropy change? Select the correct response: -0.14 kJ/kg-K 0.37 kJ/kg-K -10.0 kJ/kg-K 10.5 kJ/kg-K
