A | B |
solid | definite shape and a definite volume |
crystalline solid | this type of solid the particles form a regular repeating pattern |
amorphous solid | does not melt at a distinct temperature. Particles are not arranged in a regular pattern. |
liquid | has a definite volume but no definite shape |
surface tension | is an inward force, or pull among the molecules on the surface of a liquid that bring those molecules closer together. |
viscosity | a liquid's resistance to flowing |
gas | no definite shape and no definite volume |
volume | the amount of space that matter takes up. |
pressure | the outward force divided by the areas |
temperature | is a measure of the average kinetic energy of the particles of matter. |
melting | change in state from a solid to a liquid |
freezing | change in state from a liquid to a solid |
vaporization | change in state from a liquid to a gas (generally) |
evaporation | change in state from a liquid to a gas, happens only at the surface of the liquid |
boiling | change in state from a liquid to a gas, takes place both below and at the surface of the liquid |
condensation | change in state from a gas to a liquid |
sublimation | change in state from a solid to a gas |
Charles's law | When the temperature of a gas (at constant pressure) increases the volume increases, and when the temperature decreases the volume decreases. |
Boyle's law | When the pressure of a gas (at constant temperature) increases, the volume decreases. When the pressure is decreased, the volume increases. |
directly proportional | an increase in the independent variable causes an increase in the dependent variable |
inversely proportional | an increase in the independent variable causes a decrease in the dependent variable. |
