The pressure P (in kilopascals), volume V (in liters), and temperature (in kelvins) of a mole of an ideal gas are related by the equation PV = 8.317. Find the rate at which the pressure is changing when the temperature is 300 K and increasing at a rate of 0.1 K/s and the volume is 100 L and increasing at a rate of 0.2L/s.
