Matter
Definition
- Matter is anything that has mass and occupies space.
- It is the physical substance that makes up all objects, substances, and particles.
Properties of Matter
-
Physical Properties:
- Extensive properties: depend on the amount of matter (e.g., mass, volume)
- Intensive properties: do not depend on the amount of matter (e.g., density, color)
-
Chemical Properties:
- Reactivity with other substances
- Ability to undergo chemical changes
States of Matter
-
Solid:
- Particles are closely packed and have a fixed shape and volume.
- Examples: rocks, metals, ice
-
Liquid:
- Particles are close together but can move past each other.
- Examples: water, oil, juice
-
Gas:
- Particles are widely spaced and can move freely.
- Examples: air, helium, oxygen
-
Plasma:
- High-energy state where atoms are ionized.
- Examples: stars, lightning, neon signs
Types of Matter
-
Elements:
- Substances consisting of only one type of atom.
- Examples: hydrogen, oxygen, carbon
-
Compounds:
- Substances consisting of two or more different elements.
- Examples: water (H2O), salt (NaCl), sugar (C6H12O6)
-
Mixtures:
- Physical combinations of two or more substances.
- Examples: air, soil, blood
Changes in Matter
-
Physical Change:
- A change in state or form, but not composition.
- Examples: melting, freezing, boiling
-
Chemical Change:
- A change in composition, resulting in a new substance.
- Examples: combustion, rusting, photosynthesis
