Stack #4584383

TermDefinition
Solid: closely packed particles cause matter to have a definite shape and definite volume.
Liquid particles are free to move so a liquid has a definite volume but no definite shape.
Viscosity: A liquid's resistance to flowing. Example: Honey has a high viscosity.
Gas: particles are able to move and spread out filling all space available, thus gases have no definite shape or definite volume.
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.
Temperature the higher the temperature the faster particles move
Melting When a solid changes to a liquid
Melting point the temperature at which a substance melts.
Freezing: 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.
Sublimation: When a substance changes straight from a solid to a gas.
Example Dry Ice
Solid closely packed particles cause matter to have a definite shape and definite volume.
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.
Liquid: particles are free to move so a liquid has a definite volume but no definite shape.
Surface Tension An inward force, or pull among the molecules in a liquid that brings the molecules on the surface closer together.
Viscosity A liquids’s resistance to flowing.
Example: Honey has a high viscosity.
Gas: particles are able to move and spread out filling all space available, thus gases has no definite shape or definite volume.
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.
Temperature: the higher the temperature the faster particles moving.
