I have a cylinder sitting in my lab that contains 0.500 L of 25.85 C gas, and it's pressure is 14.7 psi. If I push the cylinder and increase the pressure to 22.6 psi and the temperature to 59.85 C, what will be the new volume of the gas in L?

Hey,

I believe you'd need to use Boyle's Law, pV=k=nRT.

P = the pressure of the gas
V = the volume of the container the gas occupies
N = the number of molecules of gas in the container
kB = Boltzmann's constant
T = the temperature of the gas in K°

What have you done so far?

Using the example of the sealed cylinder above, the volume of gas at the start is 50 cm3 with a pressure of 1.2 x 105 Pascals. The piston is pushed slowly into the syringe until the pressure on the gauge reads 2.0 x 105 Pascals. What is the volume of gas?

I'm still not understanding this. I'll keep practicing though.
