Question
Suppose 2500J of heat are added to 2.2mol of argon gas at aconstant pressure of 120kPa. Assume that the argon can be treatedas an ideal monatomic gas. a)Find the change in internal energy. 1247J wrong b) find the change in temperature for this gas. 54.70 Kcorrect c) calculate the change in volume of this gas. 1.039e-2m^3wrong I need help with parts a and c.Thank you so much!

Qp = 2500 J, n = 2.2 mol, P = 120 kPa, M = ,Cp = 5R/2 a) Qp = nCpT = (5/2) nRT U = (3/2)nRT = (3/5)Qp = 1500 J c) Qp = nCpT = (5/2) nRT = 2.5PV V = Qp/(2.5P) = 8.33*10-3m3
