TermDefinition
solid a definite shape
gas a thing that moves around freely
liquid a thing that take the shape of its container
Crystalline solids particles form a regular repeating pattern called crystals. Example: salt, sugar, and snow.
Amorphous solids particles not arranged in a repeating pattern. Example: Glass, plastic, and rubber.
Surface Tension An inward force, or pull among the molecules in a liquid that brings the molecules on the surface closer together.
Viscosity A liquid's resistance to flowing. Example: Honey has a high viscosity.
Temperature the higher the temperature the faster particles move.
Sublimation When a substance changes straight from a solid to a gas. Example: Dry Ice
Melting When a solid changes to a liquid
Melting point the temperature at which a substance melts
the temperature at which a substance melts When a liquid changes to a solid
Freezing point the temperature when a substance freezes.
Vaporization When a liquid changes to a gas
Evaporation takes place only on the surface of the liquid
Boiling When vaporization occurs both below the and at the surface.
Boiling Point Temperature at which a liquid boils.
Condensation When a gas changes to a liquid.
Pressure gas particles constantly collide with one another and the walls of their container. Pressure is the outward push divided by the area of the walls of the container. Pressure= Force/Area.
Charlesā€™s Law When the temperature of a gas at a constant pressure is increased the volume is increased, if the temperature is decreased then the volume is decreased.
Directly proportional as one amount increases, another amount increases at the same rate.
Boyle's Law When the pressure of a gas at a constant temperature is increased the volume is decreases, if the temperature is decreased then the volume is increases.
inversely proportional When the value of one variable increases, the other decreases.
