Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition.

What happens during a chemical change?

Back

During a chemical change, new substances are formed, and the original substances lose their properties.

Front

What is an example of a chemical change?

Back

Burning wood in a campfire is an example of a chemical change, as it produces ash, smoke, and gases.

Front

What is an example of a physical change?

Back

Melting ice into water is an example of a physical change, as the substance remains H2O.

Front

Why is burning a campfire considered a chemical change?

Back

Because it creates new substances with new properties, such as smoke and ash.

Front

What remains the same after a physical change?

Back

The chemical properties of the substance remain the same after a physical change.

Front

What is the difference between a chemical change and a physical change?

Back

A chemical change results in new substances, while a physical change does not change the chemical composition.

Front

What is an indicator of a chemical change?

Back

Indicators of a chemical change include color change, gas production, and temperature change.

Front

What happens to the molecules during a physical change?

Back

The molecules may change their arrangement or state but do not change their identity.
