Two kilograms of carbon dioxide expand in a cylinder at a constant temperature of 24ºC from a pressure of 800 kPa to 100 kPa. Assuming a quasi-equilibrium process, the required heat transfer is nearest:
A) 401 kJ
B) 354 kJ
C) 267 kJ
D) 233 kJ
D) 233 kJ
The heat transfer and work are equal for an isothermal process
Q = W = mRT 1n P1/P2 = 2x0.1889x297x1n800/100 = 233 kJ
