Matter
Structure and Property of Matter
Term | Definition |
---|---|
Substance | Any form of matter that is uniform throughout and has consistent properties. |
Crystal | Solid material whose atoms, molecules, or ions are arranged in an ordered pattern. |
Molecule | Two or more atoms held strongly together by covalent bonds. |
Atom | The building blocks of all matter; the smallest unit that retains the chemical properties of an element. |
Solid | A state of matter with a definite volume and shape. |
Chemical Reaction | The process by which one or more substances change to produce one or more different substances. |
Matter | Has mass and takes up space and occurs as elements, compounds, and mixtures. |
Solubility | Measurement of the ability of a solid to dissolve in a liquid. |
Chemical Properties | Characteristics that can only be observed or measured when atoms of matter rearrange during a chemical change. |
Synthetic Materials | Materials made by humans. |
Density | The amount of matter in a given space or volume; it is a relationship between mass and volume. Less dense matter will form layers above dense matter. |
Pure Substance | A single substance, either an element or a compound, with definite composition and properties. |
Natural Resources | Resources that exist in the environment without human intervention. |
Bulk Quantities | Large Quantities |
Physical Properties | Characteristics that can be observed or measured without changing the substance, such as color, melting point, or conductivity. |
Liquid | A state of matter with a definite volume but no definite shape. |
Vibrate | To move rhythmically and steadily; oscillate. |
Gas | A form of matter with indefinite shape and volume. |
Atom | The smallest particle of an element made of electrons, protons, and neutrons. |
Collide | To strike or hit something with great force. |
Inert | Used to describe a substance that is not chemically reactive. |
Thermal Energy | It is the total kinetic (motion) energy of tiny particles that make up matter. The faster the particles move, the warmer the matter becomes. |
