100

The three most common states of matter.

What are solid, liquid, and gas?

100

The change from a solid to a liquid.

What is melting?

100

Energy must be added or removed for matter to do this.

What is change state?

100

When a solid is heated, its particles do this.

What is speed up?

100

What is melting point?

The temperature at which a solid becomes a liquid.

200

Matter in this state has a definite shape and volume.

What is a solid?

200

The change from a liquid to a solid.

What is freezing?

200

When particles gain energy, they move this way.

What is move faster?

200

When a liquid cools, particles do this.

What is slow down?

200

The temperature at which a liquid becomes a gas.

What is boiling point?

300

Matter in this state takes the shape of its container but keeps its volume.

What is a liquid?

300

The change from a liquid to a gas throughout the liquid.

What is boiling?

300

Heat absorbed during a state change without temperature increase.

What is latent heat?

300

What is evaporation?

Particles escaping from the surface of a liquid create this process.

300

The pressure exerted by vapor particles in equilibrium with a liquid.

What is vapor pressure?

400

Matter in this state spreads out to fill its entire container.

What is a gas?

400

The change from a gas to a liquid.

What is condensation?

400

What is heat of fusion?

The energy required to change a solid into a liquid.

400

The movement of particles increases when this increases.

What is temperature?

400

The process where a solid turns directly into a gas.

What is sublimation?

500

A change in temperature or pressure can cause matter to do this.

What is change state or change phase?

500

What is deposition?

The change from a gas directly to a solid.

500

The energy required to change a liquid into a gas.

What is heat of vaporization?

500

When particles lose energy, they move this way.

What is move slower?

500

What is a eutectic mixture?

A mixture where substances melt easier when combined.
