When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV 1.4 = C, where is a constant. Suppose that at a certain instant the volume is 500 cm and the pressure is 80 kPa and is decreasing at a rate of 10 kPa/min. At what rate is the volume increasing at this instant?

A sample of gas at 760 torr and 2.8 L is compressed at constant temperature to the pressure at 3.5 atm. What is the final volume of the gas? My biggest problem with answering this question is the fact that I don't know what the "constant temperature" is..I know I'm using the combined gas law with formula: V2= p1v1/t1p2 * T2 and that p1=760 torr or 1 atm, v1=2.8L and p2=3.5 atm... Any help on this is very much appreciated.

Please answer all parts of the question: a,b,c,d
Ideal Gas Law The ideal gas law states that PV = Nk T where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant kg is called the Boltzmann constant and has the value kg = 1.38x10-29 J/K. A very common expression of the ideal gas law uses the...
