Temperature and Pressure

A balloon was tied to a mailbox outside in the sun. When brought inside, the balloon became slightly smaller. Which of the following best describes why this occurred?

• The particles in the balloon slowed down, so they collided with the balloon more frequently.

• The particles in the balloon slowed down, so they collided with the balloon less frequently.

• The particles in the balloon sped up, so they collided with the balloon more frequently.

• The particles in the balloon sped up, so they collided with the balloon less frequently.
