100

This state of matter has a definite shape and volume

What is a solid

100

The amount of matter in an object, typically measured in grams or kilograms.

What is mass?

100

This theory explains that all matter is made up of tiny, constantly moving particles.

What is the particle theory of matter?

100

The process of a liquid becoming a solid.

What is freezing?

100

When most substances are heated, they do this.

What is expand?

200

This state of matter has a definite volume but takes the shape of its container

What is a liquid?

200

The amount of space an object occupies.

What is volume?

200

According to the particle theory, these forces hold particles together.

What are intermolecular forces?

200

The process of a solid becoming a liquid.

What is melting?

200

When most substances are cooled, they do this.

What is contract?

300

This state of matter has neither definite shape nor definite volume.

What is a gas?

300

The measure of how much mass is contained in a given volume.

What is density?

300

In this state, particles are closely packed in a fixed arrangement.

What is the solid state?

300

The process of a liquid becoming a gas at the surface of the liquid.

What is evaporation?

300

This term describes the increase in volume of a substance due to heating.

What is thermal expansion?

400

The process by which a solid turns directly into a gas without becoming liquid first.

What is sublimation?

400

The temperature at which a solid becomes a liquid.

What is the melting point?

400

In this state, particles are close together but can move past one another.

What is the liquid state?

400

The process of a gas becoming a solid without passing through the liquid state.

What is deposition?

400

This device demonstrates thermal expansion by showing the bending of a metal strip.

What is a bimetallic strip?

500

The change of state from a gas to a liquid.

What is condensation?

500

The temperature at which a liquid changes to a gas.

What is the boiling point?

500

In this state, particles are far apart and move freely.

What is the gaseous state?

500

The energy required to change a substance from solid to liquid at its melting point.

What is heat of fusion?

500

The phenomenon where bridges have gaps to allow for this.

What is thermal expansion?
