Chapter 3 - States of Matter
pressure
the amount of force exerted on a given area
change of state
the change of a substance from one physical form to another
condensation
the change of state from a gas to a liquid
vaporization
the change of state from a liquid to a gas; includes boiling and evaporation
freezing
the change of state from a liquid to a solid
sublimation
the change of state from a solid to a gas
melting
the change of state from a solid to a liquid
Charles's Law
the law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as its temperature increases, and the volume of the gas decreases as its temperature decreases
Boyle's Law
the law that states that for a fixed amount of gas at a constant temperature, the volume of the gas increases as its pressure decreases and the volume of the gas decreases as its pressure increases
states of matter
the physical forms in which a substance can exist; states include solid, liquid, gas, and plasma
gas
the state in which matter changes in both shape and volume
solid
the state in which matter has a definite shape and volume
liquid
the state in which matter takes the shape of its container and has a definite volume
plasma
the state of matter that does not have a definite shape or volume and whose particles have broken apart
evaporation
vaporization that occurs at the surface of a liquid below the liquid's boiling point
boiling
vaporization that occurs throughout a liquid
