What else increases when density increases?

Explanation:
Density is mass per volume, and for gases it relates to pressure through ρ = PM/RT. If density increases while temperature and molar mass stay the same, the pressure must rise. More particles per unit volume collide with the container walls more often, increasing pressure. Volume or mass don’t have to increase together in this context, and temperature isn’t required to rise for the density–pressure link to show a higher pressure.
