Back

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

Front

What is an example of a physical change?

Back

Front

What is the physical state of matter that has a definite volume but takes the shape of its container?

Back

Liquid.

Front

List the characteristics of a solid.

Back

Back

Density is a physical property.

Front

What is the formula for density?

Back

Density = Mass / Volume.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
