Which statement explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant?
•
An increase in pressure causes particles to move closer together, increasing the volume.
An increase in pressure causes particles to move farther apart, 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.
1 answer
The correct statement is:
An increase in pressure causes particles to move closer together, decreasing the volume.
As pressure increases in a gas (while keeping the temperature constant), the gas particles are forced closer together, leading to a decrease in volume, according to Boyle's Law.
