1

Name the three states of matter

Liquid
Gas
Solid

2

What are the characteristics of a liquid state

A liquid state has a definite volume and definite weight but no definite shape of their own but will take the shape of the container holding them

3

what two factors influence the state that matter exists in?

temperature and pressure

4

Define specific gravity as it applies to solids or liquids.

It is the comparison of a volume of a substance (liquid or solid ) compared to an equal volume of water.
