Problem

One mole of an ideal gas is heated at constant pressure from

0^\circ\text{C}

100^\circ\text{C}

. (a) Calculate work done. (b) If the gas was expanded isothermally and reversibly at

0^\circ\text{C}

from 1 atm to some other pressure

P_f

, what must be the final pressure if the maximum work is equal to the work involved in (a)?
