Study Notes
Matter
- Anything that occupies space and has mass is called matter.
- All living and non-living things are made of matter.
States of Matter
- Matter exists in three states: solid, liquid, and gas.
Solids
- Molecules in solids are packed tightly with strong forces of attraction.
- No space between molecules to move around.
- Solids have a definite shape and size.
- Solids have a fixed volume.
- Solids occupy space.
- Solids cannot flow.
- Solids have very little or no space between molecules, making them compact and hard to compress.
Liquids
- Molecules in liquids have empty spaces between them.
- Liquids do not have a definite shape.
- Liquids have a definite volume.
- Liquids can flow.
- Force of attraction between molecules is less strong than in solids.
- Liquids can be compressed, but not as much as gases.
- Liquids occupy space.
Examples
Examples of Solids
- Wood
- Pencil
- Rubber
- Sponge
Examples of Liquids
- Water
- Juice
- Milk
- Oil
Examples of Three States of Matter
- Solid - Iceberg
- Liquid - Water
- Gas - Air
Molecules and Atoms
Molecules
- A matter (solid, liquid, or gas) is made up of tiny particles called molecules.
- Molecules are so tiny they cannot be seen with naked eyes.
- A molecule is the smallest unit of matter that has all the properties of that particular matter.
- A molecule can be further broken down into atoms.
Atoms
- An atom is the smallest unit of matter.
- Atoms form a molecule, making them the smallest unit of matter.
- The states of matter vary from each other based on the arrangement of molecules.
