Question

what happens to pressure if temperature increases?
pressure decreases.
pressure stays the same.
pressure increases.

Explanation:

This is based on gas laws (like Gay-Lussac's Law or the Ideal Gas Law), which state that for a fixed volume of gas, pressure and absolute temperature are directly proportional. When temperature increases, the gas molecules move faster, colliding with the container walls more forcefully and frequently, increasing pressure.

Answer:

Pressure increases.
