Matter, Properties and Change

All matter is made up of extremely small particles called:

• nanospecks

• dusk

• atoms

• mass

The 3 basic states of matter are:

• solid, gel, liquid

• gel, liquid, gas

• air, water, land

• solid, liquid, gas

A substance in a solid state has atoms that are;

• packed close together

• flow in a contained space

• moving freely

• large enough to see

When heat is added, a solid can become a liquid:

• true

• false

Liquids are able to change their shape by flowing:

• true

• false

If enough heat is added to a liquid, it becomes:

• gas

• melted

• solid

• compressed

When heated, the atoms in a substance:

• are destoryed

• become invisivle

• move faster

• slow down

Most substances contract when heated

• true

• false

Most substance can exit as a solid, liquid, or gas, depending on:

• density

• temperature

• mass

• volume

All substance have properties that can be classified as either:

• force or motion properties

• physical or chemical properties

• hot or cold properties

• stable or unstable properites
