Which statement explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant?

Question

an increase in pressure causes particles to move farther apart, increasing the volume
an increase in pressure cause particles to move closer together, increasing the volume
an increase in pressure causes particles to move farther apart, decreasing the volume
an increase in pressure causes particles to move closer together, decreasing the volume

Answer 1

The correct statement is:

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

This aligns with Boyle's Law, which states that for a given amount of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. Therefore, as pressure increases, the volume must decrease, resulting in gas particles being closer together.
