Study Notes
Definition of Matter
- Matter is anything that has mass and takes up space.
- It is a physical substance that has inertia and can occupy a specific location.
Properties of Matter
-
Physical Properties: characteristics that can be observed or measured without changing the composition of the matter.
- Examples: color, shape, size, texture, density, and phase (solid, liquid, or gas).
-
Chemical Properties: characteristics that describe the way a substance interacts with other substances.
- Examples: reactivity, flammability, and ability to conduct electricity.
States of Matter
- Solid: particles are closely packed and have a fixed shape and volume.
- Liquid: particles are close together but can move past each other, taking the shape of their container.
- Gas: particles are widely spaced and can move freely, expanding to fill their container.
- Plasma: a high-energy state where particles are ionized, often found in stars and lightning.
Classification of Matter
- Elements: substances consisting of only one type of atom.
- Compounds: substances consisting of two or more different elements chemically bonded together.
-
Mixtures: combinations of two or more substances that are not chemically bonded.
- Homogeneous Mixtures: uniform composition throughout, such as air or sugar water.
- Heterogeneous Mixtures: non-uniform composition, such as sand and water.
Changes in Matter
-
Physical Changes: changes in form or state, but not in composition.
- Examples: melting, freezing, evaporation, and condensation.
-
Chemical Changes: changes in composition, resulting in a new substance.
- Examples: combustion, rusting, and digestion.
