States of matter – the different forms in which matter can exist
The state of a substance is determined by thearrangement of molecules that make up the substance.
Plasma is considered the 4th state of matter althoughit does not exist naturally on Earth.
Plasma makes up most of our universe and is found instars and the interstellar environment.

Changing states – all matter can change from one state to another state
State of matter changes occur when heat energy is added to or removed from a substance.
There are five processes that can change the state of matter.
freezing
melting
sublimation
condensation
vaporization
Freezing is the change in state from a liquid to a solid that occurs when a substance loses heat energy.
remove heat
Melting is the change in state from a solid to a liquid that occurs when a substance absorbs heat energy.
add heat
Vaporization is the change in state from a liquid to a gas that occurs when a substance absorbs heat energy.
add heat
Condensation is the change in state from a gas to a liquid that occurs when a substance loses heat energy.
remove heat
Sublimation is the change in state from a solid directly to a gas that occurs when a substance absorbs heat energy.
add heat
freezing
melting
1. change in state from a liquid to a solid2. heat energy is removed or lost
1. change in state from a solid to a liquid2. heat energy is added or absorbed
Examples
Examples
vaporization - change in state from a liquid to a gas
1. evaporation -
2. boiling -
occurs at the surface of the liquid
occurs throughout the liquid when a liquid reaches a certain temperature(boiling point)
condensation
sublimation
1. change in state from a gas to a liquid2. heat energy is removed or lost
1. change in state from a solid directly to a gas2. heat energy is added or absorbed
