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.

Plasma is made up of electrically charged particles.

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)

Two types of vaporization:

1. evaporation

2. boiling

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
