A container having \( 1 \mathrm{~mol} \) of a gas at a temperature \( 27^{\circ} \mathrm{C} \) has movable piston which maintains constant pressure of \( 1 \mathrm{~atm} \) in container. The gas is compressed until temperature becomes \( 127^{\circ} \mathrm{C} \). The work done is \( \left(C_{p}\right. \) for gas is \( \left.7.03 \mathrm{cal} / \mathrm{mol}-\mathrm{K}\right) \)
(a) \( 703 \mathrm{~J} \)
(b) \( 831 \mathrm{~J} \)
(c) \( 121 \mathrm{~J} \)
(d) \( 2035 \mathrm{~J} \)
