The pressure (in kilopascals), volume (in liters), and temperature (in kelvins) of a mole of an ideal gas are related by the equation PV=8.31T . Find the rate at which the volume is changing when the temperature is 280 K and increasing at a rate of 0.1 K/s and the pressure is 10 and increasing at a rate of 0.03 kPa/s.
