What happens during a physical change?

The matter changes into a new substance

Only the appearance or state of the matter changes

The atoms rearrange into a new molecule

Energy is always released in the form of heat

What stays the same in a physical change?

The size of the substance

The smell of the substance

The chemical composition of the substance

The texture of the substance

Which is an example of a physical change?

Melting ice cream

Burning wood

Baking bread

Iron rusting

What is a clue that a physical change has occurred?

A new odor appears

Shape changes

Gas is produced

Color changes

What is a chemical change?

A change in the size of a substance

A change in the volume of matter

A change in temperature

A change that produces a new substance 

What happens when yeast is added to dough?

The yeast reacts with sugar and releases carbon dioxide

The dough changes color

The dough freezes

The yeast cools the dough

Which of the following is a clue of a chemical change?

Cutting paper

Formation of a gas

Freezing water

Melting metal

What does the Law of Conservation of Mass state?

Matter can disappear in a chemical change

Mass can be created during reactions

Matter is not created or destroyed, only changes form

Only gases follow this law

Why is sugar dissolving in water a physical change?

Because the sugar chemically reacts with water

Because a gas is produced

Because the sugar forms a new substance

Because the sugar molecules stay intact and mix with water
