Matter

What is Matter?

Solids : The Atoms and Molecules in a solid

• The Atoms & Molecules are very attracted.
• They vibrate but do not move past each other.
• They also have a definite volume and shape

This is a representation of the atoms and molecules in a solid

LIQUIDS : THE ATOMS AND MOLECULES OF A liquid

• The Atoms & Molecules of a liquid are attracted.
• They vibrate but can move past each other
• They have a definite volume, but not shape

This is a representation of the Atoms & Molecules in a liquid

Gases : The Atoms and Molecules in gases

• The Atoms & Molecules in gases are barely attracted
• They vibrate and move freely past each other
• They have no definite shape or volume

Here is a representation of the Atoms and Molecules in gases

When you add heat, Molecules & Atoms move faster and get farther apart

When you remove heat, Atoms and Molecules move slower and get closer together
