The correct statement that explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant is:

An increase in pressure causes particles to move closer together, decreasing the volume.

This reflects Boyle's Law, which states that for a given mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. As pressure increases, the volume decreases, leading to gas particles being pushed closer together.
