For an ideal gas with fixed n and V, what happens to P when the temperature increases?

Explanation:
When n and V are fixed, pressure changes directly with temperature. From PV = nRT, solve for P to get P = (nR/V) T. The factor (nR/V) is constant, so P increases linearly as T increases. Physically, hotter gas means faster-moving molecules that collide with the container walls more forcefully, raising the pressure. So as temperature goes up, pressure goes up proportionally.
