Problem

A sample of ideal gas is taken from

1.0\,\text{L}

5.0\,\text{L}

300\,\text{K}

by two different methods. Method I: slow reversible isothermal expansion. Method II: sudden expansion against a constant external pressure equal to the final equilibrium pressure of

0.5\,\text{atm}

. Which statement correctly compares the magnitude of work done by the gas,

W_I

and

W_{II}

? a)

W_I < W_{II}

W_I = W_{II}

W_I > W_{II}

d) Both

W_I

\text{and}

W_{II}

\text{are zero}
