Sections $14\mathrm{.}2$ and $14\mathrm{.}3$ provide useful information for this problem. When a monatomic ideal gas

expands at a constant pressure

of $7\mathrm{.}3$ x $105$ Pa$,$ the volume of the gas increases by $7\mathrm{.}8$ x $10-3$ m$3.$ Determine the heat that flows.

If heat flows into the gas, then the heat flow is positive. If the heat flows out of the gas, then

the heat flow is negative.
