What is Thermodynamics: Work and Heat Concepts about?
Here are the key steps to solve this problem: 1) Given: ΔU = -17.25 kJ, V1 = 140 L, V2 = 55 L, P = 1125.09 TORR 2) Use the ideal gas law: PV=nRT 3) For a constant pressure process: W = -PΔV 4) First law: Q = ΔU + W 5) Substitute the given values and convert units to obtain the heat transferred. The heat transferred is Q = -17.25 kJ + (1125.09 TORR)×(140-55)L = -17.25 kJ + 17.25 kJ = 0 kJ
