#### Definitions

fluid non-solid state of matter in which the atoms or molecules are free to move past each other
kinetic theory of matter -matter is made of atoms and molecules
-atoms and molecules act like tiny particles that are always in motion
-the higher the temperature, the faster they move
-at the same temperature, more massive particles move slower than less massive ones
solid definite shape and volume
liquid changes shape, not volume
gas changes both shape and volume
compressed close together
plasma state of matter that consists of free-moving ions and electrons; does not have a definite shape or volume
ionized electrically charged
energy the capacity to do work
kinetic energy energy of motion
temperature measure of how hot or cold something is; specifically a measure of the average kinetic energy of the particles in an object
thermal energy total kinetic energy of a substance's atoms
evaporation the change of state from a liquid to a gas
sublimation the process in which a solid changes directly into a gas
condensation the change of state from a gas to a liquid
law of conservation of mass mass cannot be created or destroyed
law of conservation of energy energy cannot be created or destroyed
pressure the amount of force exerted per unit area of a surface
pascal the SI unit of pressure; equal to the force of 1 N exerted over an area of 1 square meter
P =force/area
=F/A
buoyant force the upward force that keeps an object immersed in or floating on a fluid
viscosity the resistance of a gas or liquid to flow
Bernoulli's Principle as the speed of a moving liquid increases, the pressure of the moving fluid decreases
gas laws the laws that state the mathematical relationships between the volume, temperature, pressure and quantity of a gas
Boyle's Law for a fixed amount of gas at a constant temperature, the volume of a gas increases as the gas's pressure decreases
Boyle's Law (pressure1)(volume1) = (pressure2)(volume2)
P1V1 = P2V2
Guy Lussac's Law the pressure of a gas increases as the temperature increases, if the volume of the gas does not change
Charles' Law for a fixed amount of gas at a constant pressure, the volume of a gas increases as the gas's temperature increases
