What is the importance of pressure in determining the number of particles in a gas

[From: ] [author: ] [Date: 12-12-23] [Hit: ]
If V, R and T are constant, then you have P = n or pressure is = moles (particles).As pressure goes up, number of particles goes up, an vice versa.......
When pressure decreases, what happens to the number of particles in a gas? Do the number of particles increase, decrease, or stay the same?

If the pressure decreases but everything else (volume, temperature) stays the same, the number of particles must decrease. You can see this from the ideal gas law.
PV = nRT
If V, R and T are constant, then you have P = n or pressure is = moles (particles). As pressure goes up, number of particles goes up, an vice versa.
