Matter by Mind Map: Matter

1. Physical changes

1.1. Phase change: a change from one state (solid or liquid or gas) to another without a change in chemical composition.

1.2. Evaporation: The process of becoming a vapor

1.3. Distillation: the action of purifying a liquid by a process of heating and cooling

2. Pure substances

2.1. Compound

2.1.1. A substance that contains two or more elements chemically combined in a fixed proportion

2.2. Homogenus

2.2.1. A mixture that is uniform in composition; components are evenly distributed and not easily distinguised

2.3. Atoms

2.3.1. An atom is the smallest particle of an element that retains its identity in a chemical reaction

2.4. Element

2.4.1. The simplest form of matter that has a a unique set of properties; an element cannot be broken down into simpler substances by chemical means

2.5. Molecule

2.5.1. A neutral group of atoms joined together by covalent bonds

3. Electrolysis

3.1. A process in which electrical energy is used to bring about a chemical change; the electrolysis of water produces hydrogen and oxygen

3.2. Chemical changes

3.2.1. Chemical reaction A change in which one or more reactants change into one or more products; characterized by the breaking of bonds in reactant and the formation of bonds in products

3.2.2. Chemical Change Any process determined by the atomic and molecular composition and structure of the substances involved

4. Tryndall effect

4.1. the phenomenon in which light is scattered by very small particles in its path; it makes a beam of light visible through the liquid

5. Different Mixtures of matter

5.1. Solution

5.1.1. Emulsion a fine dispersion of minute droplets of one liquid in another in which it is not soluble or miscible

5.1.2. Suspension Components of a suspension can be evenly distributed by a mechanical means, like by shaking the contents

5.1.3. a homogeneous mixture; consists of solutes dissolved into a solvent

5.2. Mixtures

5.2.1. Mechanical Mixture a mixture whose components can be separated by mechanical means.

5.2.2. Heterogeneous Colloid A mixture whose particles are intermediate in size between those of a suspension and a solution a mixture that is not uniform in composition; components are not evenly distributed throughout the mixture

5.2.3. a physical blend of two or more substances that are not chemically combined
