Term | Definition |
solid | has a definite shape and volume |
crystalline solid | patterns create crystals, solids that are made up of crystals |
amorphous solid | particles that are not arranged in a regular pattern |
liquid | has a definite volume but takes the shape of its container |
fluid | substance that flows |
surface tension | an inward force, or pull among molecules in a liquid that brings the molecules on the surface together |
Viscosity | Liquids resistance it flowing |
Gas | Neither definite shape or volume |
Pressure | The force of its outward push divided by the area of the walls of its container |
Melting | The change of state from solid to liquid |
Melting point | In pure crystalline solids, melting occurs at a specific point |
Freezing | The change if state from liquid to solid |
Vaporization | The change of state from liquid to gas |
Evaporation | Vaporization that takes place only on the surface of a liquid |
Boiling | Vaporization that takes place both below and on the surface of a liquid |
Boiling point | The temperature at which a liquid boils |
Condensation | the change of state from a gas to a liquid |
sublimation | occurs when the surface particles of a solid gain enough energy that they form a gas |
Charles Law | when the temperature of a gas at a constant pressure increases the volume increases same way when pressure decreases the volume decreases |
Boyles Law | when the pressure is increased the volume is decreased same way if the pressure is decreased the volume is increased |
