Properties of matter
Question | Answer |
---|---|
Chemical Property | A property of matter observed only when its chemical composition changes. |
Toxicity | The quality of a substance to be poisonous |
Buoyancy | Tendency of a substance to float in a fluid. |
Viscosity | Substance's ability to flow, affected by attractive forces between molecules. |
Malleability | Ability to flatten a substance into sheets. |
Ductility | Ability to be drawn into wires |
Brittleness | Property of breaking into pieces. |
Physical Change | Change in physical properties without altering chemical composition. |
Chemical Change | Change in properties due to alteration in chemical composition. |
Kinetic Molecular Theory (KMT) | Explains behavior of atoms and molecules based on constant, random motion. |
Temperature | Average kinetic energy of particles in a substance. |
Solid | State of matter with low kinetic energy, definite shape, and volume. |
Liquid | State of matter with medium kinetic energy, indefinite shape, definite volume. |
Gas | State of matter with high kinetic energy, indefinite shape and volume. |
Reactivity | The tendency of a substance to undergo a chemical reaction. |
Flammability | The ability of a substance to catch fire or burn. |
Acidity | The ability of a substance to behave like an acid or a base. |
Physical Property | A property of matter observed without changing its chemical composition. |
Density | Amount of mass in a given volume. |
Surface Tension | Resistance of a liquid to spreading out due to attractive forces between molecules. |
Plasma | Ionized gas state of matter at high temperatures. |
Bose-Einstein Condensate | Fifth state of matter at very low temperatures where atoms act in unison. |
Phase Change | Matter transitioning between states without altering chemical composition. |
Melting Point of Water | 0 degrees Celsius |
