The Pressure $P$ (In Kilopascals), Volume $V$ (In Liters), and Temperature $T$ (In $^\circ$

Essay

The pressure $P$ (in kilopascals), volume $V$ (in liters), and temperature $T$ (in $^\circ$ K) of a mole of an ideal gas are related by the equation $P = \frac { 8.31 T } { V }$ . Find the rate at which the pressure is changing when the temperature is 300 $^\circ$ K and increasing at a rate of 0.1 $^\circ$ K/s and the volume is 100 L and increasing at a rate of 0.2 L/s.
