What can you infer about the strength and direction of forces experienced by the pod and space station when they collided?

• In the collision, the strength of the force exerted on the pod is greater than the strength of the force exerted on the space station, but those forces are exerted in opposite directions.

• In the collision, the strength of the force exerted on the space station is greater than the strength of the force exerted on the pod, but those forces are exerted in opposite directions.

• In the collision, the strength of force exerted on the pod and space station is the same, but those forces are exerted in the opposite direction.

Measurements inside a sealed container show that the pressure exerted by a gas increases as the thermal energy of the gas increases. Which of the following best explains the pressure increase?

• The gas molecules move faster and strike the container walls more often.

• The gas molecules begin to bond together into heavier molecules.

• The gas molecules radiate energy in the form of nuclear particles.

• The gas molecules stick to the walls of the container.

A balloon is inflated with room-temperature air and then put in a sunny place. The balloon expands slightly due to a rise in temperature. Which of the following best describes the molecules of air inside the balloon when the balloon is left in the sunlight as compared to when it was first inflated?
