Problem

One mole of a monoatomic ideal gas, initially at

1.0\,\text{atm}

and

300\,\text{K}

, undergoes two separate reversible processes from volume

V_i

W_{\text{iso}}

and

W_{\text{adi}}

be the magnitudes of the work done in the two processes, respectively. Calculate the ratio

\dfrac{W_{\text{iso}}}{W_{\text{adi}}}

. (a)
