Answer
304.2 K
Work Step by Step
Here we use the equation $\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}$ to find the temperature $T_{2}$
$\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}=>T_{2}=\frac{P_{2}}{P_{1}}T_{1}$
Let's plug known values into this equation.
$T_{2}=\frac{3.01\times10^{5}Pa(284\space K)}{2.81\times10^{5}Pa}=304.2\space K$
