Chemistry Vocabulary
| Term | Definition |
|---|---|
| matter | anything that has mass and takes up space (has volume) |
| atom | particle that makes up matter |
| element | a substance made of atoms that are identical |
| temperature | The measurement of the amount of kinetic (or motion) energy within a substance |
| melting point | The temperature where a substance turns from a solid to a liquid |
| boiling point | The temperature where a substance turns from a liquid to a gas |
| solubility | The ability for a substance to dissolve |
| solute | The substance that is being dissolved in a solution |
| solvent | The substance that is dissolves the solute |
| phase change | The process of a substance going from one phase of matter to another without changing any chemical properties |
| compound | a substance formed when two or more chemical elements are chemically bonded together |
| Heterogenous Mixture | a combination of two or more pure substances in which the original substances retain their chemical properties |
| Homogenous Mixture | has uniform composition and properties throughout |
| Solution | consists of a solute and a solvent |
| Atomic Mass | average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally-occurring element |
| Atomic Number | the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table |
| Periodic Table | chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns |
| evaporation | process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure |
| condensation | conversion of a substance (as water) from the vapor state to a denser liquid or solid state |
| Sublimation | the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase |
| melting | a physical process that results in the phase transition of a substance from a solid to a liquid |
| deposition | direct solidification of a vapor by cooling; the reverse of sublimation |
| freezing | process through which a substance changes from a liquid to a solid |
| volume | quantity of three-dimensional space occupied by a liquid, solid, or gas |
| density | the ratio between mass and volume or mass per unit volume |
| mass | measure of the amount of matter in an object |
| weight | name of the force exerted on an object due to the acceleration of gravity |
| ductility | physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking |
| maleability | reason metals bend or dent when struck |
| conductivity | a material's ability to conduct electricity |
| luster | the way light interacts with the surface of a crystal, rock, or mineral |
| magnetism | fundamental property of some materials (for example, iron) and electrical currents by which they are capable of exerting a force on magnets |
