According to the ideal gas law, PV=nRT
If we replace nR/V by a single constant k to make life easier we get P=kT
If we increase T...P should...increase as well?
So it would seem hotter temperatures have higher air pressures?

AIR WHEN HEATED EXPANDS RAISING THE PRESSURE. WHEN COOLED IT CONTRACTS LOWERING THE PRESSURE. HEATING AIR CAUSES THE MOLECULES TO TAKE UP LESS ROOM, AND VICE VERSA WHEN COOLED.

Because it is less dense, and that is why hot air rises and cold air falls.

Cold air is more spacious, because cold is when colliding particles are separate from each other.
And hot air, is more dense because of its nearby collision rate.
That's why cold is cold, and hot is hot.
