The pressure, volume, and temperature of a mole of an ideal gas are related by the equation $$PV = 8.31T$$, where P is measured in kilopascals, V in liters, and T in Kelvins. Use differentials to find the approximate change in the pressure (in kPa) if the volume increases from 14 L to 14.6 L and the temperature decreases from 350 K to 340 K. (Note whether the change is positive or negative in your answer. Round your answer to two decimal places.)
