Physical Properties & Density, Chemical Changes

Front

What happens to the kinetic energy of a substance when it melts?

Back

The kinetic energy increases.

Front

How can you differentiate between two substances that look identical?

Back

You can use density to tell them apart.

Front

What is mass?

Back

Mass is how much matter is in an object.

Front

How does the mass of an object change when moving from Earth to the Moon?

Back

The mass will stay the same.

Front

What is density?

Back

Density is the mass of a substance divided by its volume.

Front

How do you calculate the volume of an irregular object?

Back

You can use the water displacement method.

Front

What is the formula for density?

Back

Density = Mass / Volume.

Front

If two liquids have the same volume but different masses, which one is denser?

Back

The liquid with the greater mass is denser.

Front

What is the relationship between mass and volume in determining density?

Back

Density increases with mass if volume remains constant.

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed without changing its identity.
