Question
n moles of an ideal gas are in a cylinder fitted at one end with a movable piston. The initial temperature of the gas is Ti and the pressure is constant. Find an expression for the final temperature of the gas after work W has been done on it. Tf = n moles of an ideal gas are in a cylinder fitted at one end with a movable piston. The initial temperature of the gas is Ti and the pressure is constant. Find an expression for the final temperature of the gas after work W has been done on it. Tf = Find an expression for the final temperature of the gas after work W has been done on it. Tf =Explanation / Answer
Work done at constant pressure = integral PdV
W = PVf - PVi
W = nRTf - nRTi
Tf = [W/(nR) + Ti] where R is universal gas constant.
