Question: The pressure, volume and temp. of an ideal gas are related by the equation: PV=nRT. where P is menasured in KPA(kilo pascals), V in liters, and T in kelvins. Use differentials to find the approximate change in the pressure if the volume increases from 12L to 12.3L and the temperature decreses from 310K to 305K. Any idea how to do this?

Thank you
