1.00 mol of an ideal gas (the system) is confined in a piston and cylinder
assembly similar to that shown in figure on right. The initial temperature is
300. K, and the initial pressure is 0.200 bar. The surroundings are a water
bath at 300. K.
a. Write an expression in terms of the system variables for the work in a
reversible process in which the volume of the gas is doubled.
b. Can you obtain a numerical value for w? Assume that the reversible
process is isothermal. Calculate w by evaluating the integral in part (a).
