| Term | Definition |
|---|---|
| STATES OF MATTER | Solid, Liquid, Gas |
| PHASES OF MATTER | Freezing, Melting, Evaporating, Condensation |
| BOILING POINT | Temperature at which liquid turns into a gas 100o Celsius, 212o Fahrenheit and ABOVE “Phase Change” in the state of matter |
| COMPOUND | Substance formed when 2 or more chemical elements are chemically bonded together i.e., Pure water –a compound (2 elements - hydrogen & oxygen) Pure table salt –a compound (2 elements - sodium & chlorine) |
| CONDENSATION POINT | Point at which gas turns into liquid 100o Celsius, 212o Fahrenheit and BELOW “Phase Change” in the state of matter |
| FREEZING POINT | Temperature at which a liquid turns into a solid 0° Celsius, 32° Fahrenheit and BELOW “Phase Change” in the state of matter |
| GAS | a “State of matter “ No precise shape or volume Particles are spread apart Molecules in constant motion |
| HETEROGENEOUS | NOT the same throughout NOT uniform (non-uniform) |
| HOMOGENEOUS | same throughout or uniform i.e., Coffee, Chocolate Ice Cream |
| LIQUID | a “State of matter“ Definite volume No fixed shape; assumes shape Molecules move freely |
| MELTING POINT | Temperature at which a solid turns into a liquid 0o Celsius, 32o Fahrenheit and ABOVE “Phase Change” in the state of matter |
| MIXTURE | Two or more substances Mixed together but not chemically combined |
| SOLID | a “State of matter” Definite density and shape Molecules are closely packed Fix volume and shape |
| SOLUTION | ONE substance evenly dispersed in another a/k/a Homogeneous mixture |
| SOLVENT (solute) | It is a substance! (usually liquid) Dissolves other substances Example of a solvent is ________. Acetone for nail polish ru/e/emover Paint thinner for paints |
| SUBSTANCE | Form oaf matter With a uniform chemical structure SAME properties and composition Either an element or a compound |
