Extracted text: A sample of 1 mol ammonia is heated from an initial temperature of 298 K to a final temperature of T2 at constant pressure of 1 atm until the volume has increased by a factor of 3 (V;=3V1). Calculate q, w, AH, AU and AS for this process. (Assume ideal gas behaviour). The constant-pressure heat capacity of ammonia varies with temperature according to the expression given below. Cp,ammonia (cal/K) = 6.2 + 7.9×10³T - 7.3x107T
