If the pressure goes up, would that mean the volume would go down?

yes

yes, pressure and volume are inversely proportional (this is called Boyle's Law)

Yes, if you think about it, the higher the pressure is, the less room there is for particles to move around.

If temperature is held constant and there's a decrease in volume, the same amount of molecules will be moving in a smaller space and will collide more often, leading to an increase in pressure. If volume increases, molecules will have more space and collide less frequently, decreasing pressure.

Believe it depends on which container and context, but from what I’ve seen in the lecture, yes. It’s like, if you double the pressure, then you halved the volume. Hope this helps. :)

yes, because the molecules will have less space to move around

Can’t pressure go up with T going up from PV=nRT with no effect on volume?

Yes, pressure and volume are inversely related.
