What are the states of matter? • The volume of an object is the amount of space it takes up. • It is measured in cubic centimetres(cm3). • An object that is heavy for its volume is dense.
Solids • They stay in one place. • They do not flow. • The volume of an object is the amount of space it takes up. • Bits of solid don’t change their volumes. • They can not be squashed. • Solids are often dense.
Liquids • Liquids flow. • Liquids don’t change their volumes. • They cannot be squashed. • Liquids are quite dense but usually less dense than solids.
Gases • Gases flow very easily. • They spread out to fill whatever container they are in. • Gases do not have a fixed volume. • Gas can be squashed. • Gases are not very dense. They are all less dense than liquids.
