Physical Properties of Matter

Four States or Phases of Matter

Solid – has a definite shape and a definite volume

Example –ice, book, desk

In a solid, atoms are in a fixed position relative to each other.

Liquids – has a definite volume but no definite shape.

Takes the shape of its container

Example: water, mercury

In a liquid, the atoms are free to change position with each other.

Gas – has no definite volume and no definite shape

Example: Steam (water vapor)

In a gas, the atoms are free to move independently of each other.

Plasma - is the most common kind of matter in the universe.

Plasma is matter in the state of ions and

electrons (charged particles)

Example: stars, lightning, auroras

Add or take away – Energy

Energy – the ability to do work

Examples: heat, light, nuclear

Matter plus energy

Ice + heat = water solid melting liquid

Water + heat = water vapor liquid evaporation gas

Evaporation – is the process of changing from a liquid to a gas

Matter minus energy

Water vapor - heat = water gas condesation liquid

Condensation – is the process of changing from gas to liquid

Water – Heat = Ice liquid freezing solid

The exchange of water amoung Earth’s hydrosphere (water), geosphere (land), and atmosphere (air). (4 steps)

1. Evaporation

4. Runoff or

Groundwater

3. Precipatation

2. Condensation
