Question

what happens to pressure if volume decreases in a gas? pressure decreases. pressure stays the same. pressure increases and then decreases. pressure increases

Explanation:

This is based on Boyle's Law, which states that for a fixed amount of gas at constant temperature, pressure and volume are inversely proportional ($P_1V_1 = P_2V_2$). When volume decreases, the gas molecules collide more frequently with the container walls, increasing pressure.

Answer:

Pressure increases
