Question | Answer |
solid | has a definite shape and a definite volume |
crystalline solid | a solid with the particles forming a regular repeating pattern creating a crystal. |
amorphous solid | the particles are not arranged in a regular pattern |
liquid | has a definite volume but no shape of its own |
fluid | substance that flows (liquid or gas) |
surface | is the result of an inward pull among the molecules of a liquid that bring the molecules on surface closer together |
viscosity | a liquid's resistance to flowing depends on the size and shape of its particles and attraction between the particles. |
gas | is a fluid can change volume very easily |
melting | change in state from a solid to a liquid. |
melting point | in most pure substances melting occurs a a characteristic temperature |
freezing | the change from a liquid to a solid or the reverse of melting. The particles move so slowly that they begin to take on fixed position |
vaporization | the change from a liquid to a gas and the particles in a liquid gain enough energy to move independently. |
evaporation | when vaporization takes place only on the surface of a liquid |
boiling | occurs when liquid changes to a gas below it surface as well as at thesurface |
boiling point | the temperature a which a liquid boils |
condensation | is the change in state from a gas to a liquid |
sublimation | occurs when the surface particles of a solid gain enough energy form a gas |
pressure | of a gas is the force of its outward push divided by the area of the walls of the container measured in Pascals (Pa) |
directly proportional | when a graph of two variables is a straight line passing through the origin Charles Law |
inversely proportional | when the product of two variables is a constant Boyles Law |
