Study Notes
States of Matter
- Matter is defined as anything with mass and occupies space.
- Three primary states of matter: solid, liquid, gas.
- All matter consists of particles that are in constant motion.
- Spaces exist between the particles of matter.
Properties of Solids
- In solids, particles are closely packed and vibrate around fixed positions.
- Solids possess a definite shape and volume.
- Solid particles do not flow and cannot be compressed.
Properties of Liquids
- Liquid particles can slide past one another, allowing them to flow.
- Liquids take the shape of their container but maintain a definite volume and are nearly incompressible.
- Liquids diffuse slowly when poured from one container to another.
Properties of Gases
- Gas particles move freely and vigorously within their container.
- Gases exert pressure on container walls and can be compressed.
- Gases lack a definite shape and volume.
Physical Properties of Matter
-
Physical properties are observable characteristics without altering composition.
-
Divided into intensive and extensive properties:
Intensive Properties
- Do not depend on the amount of substance present.
- Examples include:
- Color
- Taste
- Melting Point
- Boiling Point
- Hardness
- Density
- Solubility
- Magnetism
- Luster
- Ductility
- Malleability
Extensive Properties
- Change when the amount of matter changes.
- Examples include:
- Mass
- Weight
- Length
- Shape
- Volume
Chemical Properties of Matter
- Chemical properties identify a substance's ability to react and form new substances.
- Examples include:
- Flammability
- Ability to rust
