Emma is observing tiny particles under a microscope and wonders if they must follow laws of motion like large objects.

• True

• False

Kai is inflating a balloon and notices that it can be compressed easily. The reason why gas particles in the balloon, unlike solids and liquids, can be compressed is due to the...

• The size of the particles

• The space between the particles

• Gas particles cannot be compressed

• Gas particles do not move.

Hannah is inflating a bicycle tire. The amount of force she applies on the pump over the area of the pump handle is known as...

• Mass

• Pressure

• Volume

• Space

The number of particles is the only factor that affects pressure.

• False

• True

In a crowded subway train, if there are a lot of people moving very fast, there are many collisions, so it means there is a lot of pressure. 

• True

• False

Emma and Rohan are playing a game of marbles. An elastic collision means

• There is no loss of energy in the interaction.

• There is a loss of energy in the interaction.

• Only one gas particle loses energy.

• Only one gas particle gains energy.
