States of Matter LO: I know what is meant by the three states of matter.

There are three states of matter: (1) Solids Structure: Features: flow does not . shape has its own . volume doesn’t change . neatly ordered particles. particles vibrate . slowly LO: I know what is meant by a solid.

(2) Liquids Structure: Features: flows . shape doesn’t have its own . volume doesn’t change . disordered particles. quickly particles vibrate . LO: I know what is meant by a liquid.

(3) Gases Structure: Features: flow spread and out. shape doesn’t have its own . volume changes . disordered particles. very quickly particles vibrate . LO: I know what is meant by a gas.

Changes of State LO: I understand what happens during a state change.

ice water steam Changes of State A change of state occurs when is added or taken away from a substance: heat Add heat melting boiling ice water steam Remove heat freezing condensing LO: I understand what happens during a state change.

The melting point is the temperature at which a turns into a . solid liquid The melting point of water is ˚C. The boiling point is the temperature at which a turns into a . liquid gas The boiling point of water is ˚C. 100 Evaporating is a special case of boiling that takes place below the point. boiling LO: I understand what happens during a state change.
