Study Notes
Types of Matter
- Solid: Has a fixed shape and volume. Examples: rocks, books, chairs
- Liquid: Has a fixed volume but takes the shape of its container. Examples: water, oil, juice
- Gas: Has neither a fixed shape nor a fixed volume. Examples: air, helium, oxygen
Characteristics of Matter
- Mass: The amount of matter in an object, measured in grams (g) or kilograms (kg)
- Volume: The amount of space occupied by an object, measured in cubic centimeters (cm³) or liters (L)
- Density: The mass of an object per unit volume, measured in grams per cubic centimeter (g/cm³)
Physical Properties of Matter
- Color: The appearance of an object when light is reflected or transmitted through it
- Odor: The smell of an object
- Texture: The feel of an object's surface
- Taste: The sensation of an object's flavor
- Solubility: The ability of a substance to dissolve in a solvent
- Boiling Point: The temperature at which a liquid changes to a gas
- Melting Point: The temperature at which a solid changes to a liquid
Changes in Matter
- Physical Change: A change in which the substance remains the same but its physical properties change, such as melting or boiling
- Chemical Change: A change in which the substance itself changes, such as burning or rusting
Examples of Changes in Matter
- Melting: Ice (solid) → Water (liquid)
- Boiling: Water (liquid) → Water Vapor (gas)
- Rusting: Iron (metal) → Iron Oxide (rust)
- Burning: Wood (solid) → Ash (solid) + Carbon Dioxide (gas)
Types of Matter
- Solids have a fixed shape and volume, with examples including rocks, books, and chairs.
- Liquids have a fixed volume but take the shape of their container, with examples including water, oil, and juice.
- Gases have neither a fixed shape nor a fixed volume, with examples including air, helium, and oxygen.

- Boiling point is the temperature at which a liquid changes to a gas.
- Melting point is the temperature at which a solid changes to a liquid.
Changes in Matter
- Physical changes involve a change in physical properties, but the substance remains the same.
- Chemical changes involve a change in the substance itself.
Examples of Changes in Matter
- Melting involves a solid changing to a liquid, such as ice turning into water.
- Boiling involves a liquid changing to a gas, such as water turning into water vapor.
- Rusting involves iron changing to iron oxide, resulting in rust.
- Burning involves a solid changing to a solid and a gas, such as wood turning into ash and carbon dioxide.
