Problem

A sample of ideal gas is allowed to expand reversibly from volume

V_1

V_2

(

V_2>V_1

) along two different paths. Path I: isothermal expansion at temperature

T

. Path II: adiabatic expansion. Let

W_I

and

W_{II}

be the work done by the gas along Path I and Path II respectively. Which of the following correctly compares

W_I

and

W_{II}

? (a)

W_I = W_{II}

(b)

W_I < W_{II}

(c)

W_I > W_{II}

(d) The comparison cannot be made without knowing

T
