Term | Definition |
---|---|
Solid | has a definite shape and volume |
Fluid | meaning a substance that flows |
Crystalline Solid | a solid that has a definite shape and volume and has a specific melting point |
Surface Tension | an inward force, or pull, among molecules in a liquid that brings them closer together |
Amorphous Solid | a solid that has no definite shape or volume and no specific melting point |
Viscosity | a liquids resistance to flowing |
Gas | particles with no definite shape that move to fill any container they are in |
Liquid | as a definite volume but no shape of its own |
Pressure | the force of the outward push divided by the area of the walls of its container |
Melting | the change in state from a solid to a liquid |
Melting Point | when pure crystalline solids melt at a specific temp. |
Freezing | when a liquid turns into a solid |
Vaporization | when a liquid turns into a gas |
Evaporation | vaporization that only takes place on the surface of a liquid |
Boiling | vaporization that takes place below and on the surface of a liquid |
Boiling Point | the temp at when a liquid boils |
Condensation | when a gas turns into a liquid |
Sublimation | when a solid turns into a gas without turning into a liquid first |
Charles's Law | when the temperature of a gas at a constant pressure increases its volume increases. when the temperature of a gas at a constant pressure decreases its volume decreases |
Directly Proportional | when the variables form a line the passes straight through a graphs origin(0,0) |
Boyle's Law | when the pressure of a gas at a constant temperature is increased the its volume decreases. when the pressure decreases then its volume increases. |
Inversely Proportional | when the product of two variables is constant |
