Matter-Physical and Chemical Properties and Changes

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

What are physical properties of matter?

Back

Physical properties are characteristics that can be observed or measured without changing the substance's identity, such as color, density, and boiling point.

Front

What are chemical properties of matter?

Back

Chemical properties describe a substance's ability to undergo changes that transform it into different substances, such as reactivity and flammability.

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, such as melting or boiling.

Front

What is a chemical change?

Back

A chemical change is a process that involves the transformation of one substance into another, resulting in a change in chemical composition, such as rusting or burning.

Front

Example of a physical change?

Back

Water turning to steam when boiled is an example of a physical change.

Front

Example of a chemical change?

Back

Rust forming on iron is an example of a chemical change.

Front

What is rusting?

Back

Rusting is a chemical change that occurs when iron reacts with oxygen and moisture, forming iron oxide.

Front

What is boiling?

Back

Boiling is a physical change where a liquid turns into vapor when it reaches its boiling point.

Front

What indicates a chemical change is occurring?

Back

Signs of a chemical change include color change, gas production, temperature change, and the formation of a precipitate.
