Study Notes

States of Matter

Matter is anything that occupies space and has mass.
There are three primary states of matter: solid, liquid, and gas.

Properties of Matter

Properties used to identify the state of matter include:
- Shape: Relates to the form an object takes.
- Mass: The amount of matter in an object.
- Volume: The space occupied by the matter.

Solids

Solids have a definite shape, mass, and volume.
Atoms in solids are tightly packed, giving them a fixed structure.
Example of solids includes trees, furniture (chairs), and ice.

Liquids

Liquids have a definite mass and volume but do not have a fixed shape.
The atoms in liquids are close together but can move around, allowing liquids to flow and take the shape of their container.
Common examples include milk and juice.

Gases

Gases lack a definite shape and volume, taking both the shape and volume of their containers.
Atoms in gases are much farther apart, allowing them to move freely and spread out.
Everyday examples include the air we breathe, which contains gases like oxygen and helium.

Water's Changing States

Water can exist in all three states: solid (ice), liquid (water), and gas (water vapor).
The transition from ice to water is called melting, while water vapor is produced through evaporation.

Observations in Everyday Life

Matter can be identified in various forms around us; for example, solid, liquid, and gas can often be found in a typical household setting.
A simple experiment can show the states of matter by observing the melting of ice to water and then evaporation to water vapor.
