u are living, u occupy space, u have a mass. u MATTER
Matter is anything that has mass and takes up space. We cover five states of matter on the site. Each of those states is sometimes called a phase. You should know about solids, liquids, gases, plasmas, and one state called the Bose-Einstein condensate (BEC). Solids are hard and brittle. Gases are always around you. Molecules can change a physical state without changing the basic structure of the molecule like the melting of ice. But with certain aspects like rusting and burning of metals, a chemical change of state occurs where the molecules no longer carry the same initial recognition that it once was established. 2 parts of matter are the compositions and properties. Properties branch into physical and chemical. Compositions go into mixtures and pure substances. Mixtures branch into homogenous and heterogenous. Pure substances branch into elements and compounds. Elements branch into metals and non metals. Compounds branch into inorganic to organic.
- Element- a part or aspect of something abstract, especially one that is essential or characteristic.
- Compound- is an entity consisting of two or more different atoms which associate via chemical bonds.
- Mixture-refers to the physical combination of two or more substances on which the identities are retained and are mixed in the form of solutions, suspensions, and colloids
- Heterogeneous matter- any mixture that is not uniform in composition – it's a non-uniform mixture of smaller constituent parts. Using various means, the parts in the mixture can be separated from one another.
- Homogeneous matter- simply any mixture that is uniform in composition throughout.
- Colloid- is a substance in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance.
- Suspension- a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation
- Decomposition- the state or process of rotting; decay.
- Pure substance- A material that is composed of only one type of particle
- Solution-a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).
- Physical Change- Any change that occurs without altering the chemical composition of a substance
- Chemical Change-any change that results in the formation of new chemical substances.
- Distillation- the action of purifying a liquid by a process of heating and cooling.
- Melting- make or become liquefied by heat.
- Burning- on fire.
