The pressure P (in kilopascals), volume V (in liters), and temperature T (in kelvins) of a mole of an ideal gas are related by the equation PV = 8.31T, where P, V, and T are all functions of time (in seconds). At some point in time the temperature is 275 K and increasing at a rate of 0.15 K/s and the pressure is 29 and increasing at a rate of 0.03 kPa/s. Find the rate at which the volume is changing at that time. L/s Round your answer to four decimal places as needed.
