An ideal gas at

P $=2\mathrm{.}60105$ Pa

and

T $=295$ K

expands isothermally from $1\mathrm{.}26$ m$3$ to $2\mathrm{.}73$ m$3.$ The gas then returns to its original state through a two$-$part process: constant$-$pressure followed by constant$-$volume. $($c$)$ Find the work done by the environment on the gas. $($Include the sign of the value in your answer.$)($d$)$ Find the heat that flows into the gas. $($Include the sign of the value in your answer.$)$
