Study Notes
Definition of Matter
- Matter is any substance that occupies space and has mass.
- Key properties include having mass or weight and occupying space.
Mass of Matter
- Mass is the quantity of matter in a body and remains consistent regardless of location on Earth.
Composition of Matter
- Matter is composed of tiny, invisible particles known as atoms.
- Atoms combine to form molecules, which are the smallest independent units of a substance that possess all properties of that matter.
States of Matter
Solid
- Molecules in solids are closely and tightly packed, restricting movement.
- Solids have a definite shape and volume.
- Most solids can transition to liquid form when heated (e.g., ice, iron, wax, lead).
Liquid
- Molecules in liquids are loosely packed, allowing for movement within the liquid.
- Liquids flow from higher levels to lower levels and do not have a definite shape, conforming to the shape of their container.
- They possess a definite volume and can change into gas when heated (e.g., water, oil, petrol, milk).
Gas
- Molecules in gases are very loosely packed and spaced far apart.
- Gases have neither definite shape nor volume, filling any available space.
- Gases can be compressed into smaller volumes (e.g., water vapor, air, smoke).
