Amplify Science Modeling Matter Review

Front

What are the three states of matter?

Back

Solid, liquid, and gas.

Front

What is a particle model of matter?

Back

A model that describes matter as being made up of small particles that are in constant motion.

Front

How do the properties of solids differ from liquids?

Back

Solids have a definite shape and volume, while liquids have a definite volume but take the shape of their container.

Front

What happens to the particles in a substance when it freezes?

Back

The particles lose energy and move closer together, forming a solid.

Front

What is the definition of matter?

Back

Anything that has mass and takes up space.

Front

How can you demonstrate that gas is a type of matter?

Back

By using a balloon filled with air, which shows that gas occupies space.

Front

What is the principle of conservation of mass?

Back

Mass is neither created nor destroyed in a chemical reaction; it is conserved.

Front

What are physical properties of matter?

Back

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

Front

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

Back

A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.

Front

What is density, and how is it calculated?

Back

Density is the mass of a substance divided by its volume (Density = Mass/Volume).
