Quiz # 2 Physics 230 Prof. Hadley 1. Question: NOTE : For the following problems, use these constants: R = 8.315 J/(mol K), k = 1.38 X 10 -23 J/K, PV = nRT. STP means 273K, 1 atm 1 atm = 1.013 X 10 5 Pa U = fnRT/2, where f=# of degree of freedom. Also, pay close attention to significant figures. THE PROBLEM: Refer to Figure 1 below. You have 1.0 mol of argon, an ideal monatomic gas, in a closed container at STP (Point A in Figure 1). Points B and C are on the isotherm T=423K. The cycle ABCA is moved through counterclockwise. Using the formulas above,
