Water, air, buildings, food, and everything visible and invisible has mass and takes up space. What is the word used to describe anything that has mass and takes up space?

• atom

• molecule

• solid

• matter

A pure substance is a single kind of matter.

• element

• compound

• molecule

• atom

Atoms combine to form larger particles called

• molecules

• electrons

• groups

Matter can be measured in many ways for specific purposes. Which measurement depends on the force of gravity and for that reason would not be a reliable measurement?

• mass

• weight

• volume

• temperature

The density of an object tells

• the amount of matter and object has

• the amount of volume an object occupies

• the amount of matter per unit of volume

• The shape an object has

The difference between a physical and a chemical property is that a chemical property involves the change of a substance into new substances. For example, freezing is a physical property because the freezing substance goes through a physical change (from liquid to solid), but it does not change into a different substance. Which items describe physical properties? Choose the two that apply.

• texture

• rusting

• flammability

• boiling

The amount of matter in an object reflects its

• mass

• volume

• density

• weight
