Question

One mole of nitrogen at 8 bar and 600 K is contained in a piston-cylinder arrangement. It is brought to 1 bar isothermally against a resisting pressure of 1 bar. The work done (in Joules) by the gas is

Accepted Answer

Option B. 10373. Answer & Solution Answer: Option B Solution: Assuming ideal gas behavior the isothermal work done is given as : $$ arrayl W = nRTln P_1P_2\ W = 1 * 8.321 * 2079\ So,W = 10379, nearly \, equal \, to \,W = 10373 array$$
