Explanation:
I never really took physics yet, but I do have some general knowledge of particle physics.
When pressure increases, the gas molecules will get closer together and rise in temperature, vice versa. (That's actually one way we get energy. The more pressure we apply to gas, the hotter it gets and therefore releases pretty good amounts of energy)
When temperature increases, the gas molecules will try to get away from each other and spread out, vice versa. The higher the temperature, the faster the particles move
And when volume increase, there is more room for the gas particles to bounce around and they are generally spread out from each other.
Someone else can answer if I didn't explain it correctly
