ME 200: Thermodynamics I Spring 2011 Division 1 Quiz 4 Name Sameer Naik1. A substance has a critical temperature of 150 K and a critical pressure of 50 bar. Indicate by circling one of the answers below the combination of temperature and pressure for which the substance can most appropriately be modeled as an ideal gas. You must justify your answer to receive full credit. (5 points) 50 K and 5 bar 50 K and 200 bar 1500 K and 5 bar1500 K and 200 bar Substance will behave most appropriately as an ideal gas at the highest temperature and the lowest pressure relative to the critical temperature and pressure2. A scientist at Los Alamos National Laboratory tells his supervisor that the internal energy change of an ideal gas is 1000 kJ/kg when the temperature change is 100 K and the specific enthalpy change of the same ideal gas for the same change in
