Multiple Choice

Why can gases be compressed easily while solids and liquids cannot?

Gases have a fixed volume while solids and liquids do not.

Gases have particles that are far apart and have more space to compress.

Solids and liquids have particles that are far apart and have more space to compress.

Gases have stronger intermolecular forces than solids and liquids.

Drag and Drop

In solids, particles are close together and

in place. In liquids, particles are close together but move around

and collide with each other. In gases, particles are

and move in straight lines at high speeds, colliding with each other and the walls of their container.

Multiple Choice

What is kinetic energy?

The energy stored in an object due to its position

The energy released from an object at rest

The energy generated by an object's weight

The energy an object possesses due to its motion

Multiple Choice

What is temperature?

Temperature is a measure of the distance between two points on a scale

Temperature is a measure of the amount of water vapor in the air

Temperature is a measure of the brightness of an object

Temperature is a measure of the average kinetic energy of the particles in an object or substance.

Multiple Choice

What is the relationship between temperature and kinetic energy?

Temperature and kinetic energy are inversely proportional

There is no relationship between temperature and kinetic energy

Kinetic energy decreases as temperature increases

Temperature and kinetic energy are directly proportional

Drag and Drop

At lower temperature, particles move

because they have

kinetic energy

At higher temperatures particles move

because they have

kinetic energy
