Study Notes
Definition of Matter
- Matter is anything that has mass and occupies space.
- It is the physical substance that makes up all objects, living and non-living.
States of Matter
- Solid: Has a fixed shape and volume.
- Liquid: Has a fixed volume but takes the shape of its container.
- Gas: Has neither a fixed shape nor a fixed volume.
- Plasma: A high-energy state of matter where atoms are ionized.
Properties of Matter
-
Physical Properties:
- Color
- Texture
- Odor
- Taste
-
Chemical Properties:
- Ability to react with other substances
- Ability to change composition
Types of Matter
-
Elements: Substances composed of only one type of atom.
- Examples: Hydrogen (H), Carbon (C), Oxygen (O)
-
Compounds: Substances composed of two or more different elements.
- Examples: Water (H2O), Carbon Dioxide (CO2)
-
Mixtures: Combinations of two or more substances that are not chemically combined.
- Examples: Air, Soil, Blood
Changes in Matter
-
Physical Change: A change in the state of matter without a change in composition.
- Examples: Melting, Freezing, Evaporation
-
Chemical Change: A change in the composition of matter, resulting in a new substance.
- Examples: Combustion, Rusting, Decaying
