The gas law for an ideal gas at absolute temperature $T$ (in kelvins), pressure $P$ (in atmospheres), and volume $V$ is $PV=nRT$, where $n$ is the number of moles of the gas and $R=.0821$ is the gas constant. Suppose that, at a certain instant, $P=8$ atm and is increasing at a rate of .10 atm/min and $V=10$ L and is decreasing at a rate of .15 L/min.
Find the rate of change of $T$ with respect to time at that instant if $n=10$ moles. Round your answer to the nearest thousandth.
