A cylinder contains 3 moles of oxygen at a temperature of \( 27^{\circ} \mathrm{C} \). The cylinder is provided with a frictionless piston
\( \mathrm{P} \) which maintains a constant pressure of \( 1 \mathrm{~atm} \) on the gas. The gas is heated until its temperature rises to \( 127^{\circ} \mathrm{C} \).
(a) How much work is done by the gas in the process ?
(b) What is the change in the internal energy of the gas ?
(c) How much heat was supplied to the gas ?
