Question

an SCL table? le ostmating v and u of an SCL, if you do not have access to (4) 1st Law with ideal gas A piston-cylinder device contains 5 kg of argon, initially at T35°C and Pi 100 kPa. Heat is t hen gradually added to the system until it reaches state 2 at T2-8 0°C. a) Use the compressibility factor Z to verify that Ar can be treated as ideal gas in this problem. b) Find the volumes Vi and V2. c) Find Q12. (Note: The specific heat capacities of Ar can be found in Table A-2, and because Ar is a monatomic ideal gas its specific heats are independent of temperature.!) See Fig. 4-24, which further shows that all monatomic ideal gases have the same specific heat when expressed on a ar basis (20.79 kJ/kmol-K, which is exactly Ru). This figure also shows the general trend that specific heat oase with the complexity of the molecule, from monatomic → diatomic → triatomic. 2
