Physical and Chemical Properties of Matter

Front

What is a physical property of matter?

Back

A physical property is something that can be observed about the substance by itself, such as color, density, and melting point.

Front

What is a chemical change?

Back

A chemical change occurs when a substance transforms into a different substance, often involving a reaction that produces new materials.

Front

Give an example of a chemical change.

Back

Rusting of metal is an example of a chemical change.

Front

What evidence indicates a chemical change has occurred?

Back

Evidence of a chemical change includes the production of gas, color change, temperature change, or the formation of a precipitate.

Front

What are the three states of matter?

Back

The three states of matter are solid, liquid, and gas.

Front

Describe the properties of solids.

Back

Solids have a definite shape and volume, and their particles are closely packed together.

Front

Describe the properties of liquids.

Back

Liquids have a definite volume but take the shape of their container, and their particles are less tightly packed than in solids.

Front

Describe the properties of gases.

Back

Gases have no definite shape or volume, and their particles are far apart and move freely.

Front

What happens to matter during a physical change?

Back

During a physical change, the form of matter may change, but its chemical composition remains the same.

Front

What is an example of a physical change?

Back

Melting ice is an example of a physical change.
