Term | Definition |
---|---|
Matter | Anything that has mass and volume |
Condensation | When a vapor or gas changes into the liquid phase |
Deposition | When a gas changes directly into a solid |
Freezing | When a liquid changes into the solid phase |
Fusion | Process of particles in the solid phase gaining enough energy to break into the liquid phase; aka Melting |
Gaseous Phase | A phase of matter without definite shape or volume |
Heat | Energy transferred from one substance to another; measured in calories or joules |
Heat of Fusion | The amount of heat absorbed to change a substance from a solid to a liquid at its melting point |
Heat of Vaporization | Amount of heat absorbed to change a substance from a liquid to a gas at its boiling point |
Kinetic Molecular Theory | A theory used to explain the behavior of gases in terms of the motion of their particles |
Liquid Phase | A phase of matter having definite volume but no definite shape |
Solid Phase | A phase of matter having a definite shape and volume |
Sublimation | The process in which a solid changes directly into a gas |
Temperature | Measure of the average kinetic energy of a substance’s particles |
Vaporization | Process of particles in the liquid phase gaining enough energy to break into the gaseous phase; aka boiling |
Kinetic Energy | Energy of movement |
Potential Energy | Stored energy |
Distillation | Separation by boiling |
Chromatography | Separation by polarity |
Filtration | Separation by particle size |
