100

This is anything that has mass and takes up space

What is matter
100

This state has a definite shape and definite volume.

What is a solid?

100

The change from a solid to a liquid is called this.

What is melting?

100

The measure of how fast particles move in matter.

What is temperature?

100

Ice melting into water is an example of this type of change.

What is a change of state (melting)?

200

The three main states of matter are solid, liquid, and what?

What is a gas

200

This state has a definite volume but no definite shape.

What is a liquid?

200

The change from a liquid to a solid is called this.

What is freezing?

200

Particles in this state vibrate but stay close together.

What is a solid?

200

Water boiling on the stove is an example of this process.

What is boiling?

300

This property measures how much matter is in an object.

What is mass?

300

This state has neither a definite shape nor a definite volume.

What is a gas?

300

The change from a liquid to a gas at the surface is called this.

What is evaporation?

300

Particles in this state move freely and spread out to fill space.

What is a gas?

300

Fog forming when water vapor cools in the air is an example of this.

What is condensation?

400

This property describes how much space an object takes up.

What is volume?

400

This force holds the surface of a liquid together like a “skin.”

What is surface tension?

400

The change from a liquid to a gas throughout the liquid is called this.

What is boiling?

400

Energy that causes particles to move faster and change state.

What is thermal energy?

400

Dry ice disappearing into carbon dioxide gas shows this change.

What is sublimation?

500

This property compares mass to volume.

What is density?

500

This happens when a gas turns directly into a solid.

What is deposition?

500

The change from a solid directly to a gas is called this.

What is sublimation?

500

When a substance gains or loses this, it changes state.

What is heat (energy)?

500

A puddle drying on a hot day shows this process.

What is evaporation?
