|
kinetic-molecular energy
|
is based on the idea that particles of matter are always in motion.
|
|
|
ideal gas
|
an imaginary gas that that perfectly fits all the assumptions of the kinetic molecular theory
|
|
|
fluids
|
a substance that can flow and therefore take the of its container; a liquid or gas
|
|
|
diffusion
|
spontaneous mixing of the partiles of two substances caused by their random motion
|
|
|
real gas
|
a gas that does not behave completely according to the assumptions of the kinetic molecular theory.
|
|
|
pressure
|
the force per unit area on a surface
|
|
|
atmosphere of pressure

exactly equivalent to 760 mm Hg
|
|
|
Gas Laws
|
simple, mathematical relationships between the volume, temperature, pressure, and amount of a gas
|
|
|
Boyles Law
|
states that the volume of a fixed mass of gas varies inversely with the pressure at constant temperature
|
|
|
Charles Law
|
states that the volume of a fixed mass of a gas at constant pressure varies directly with Kelvin temperature
|
|
|
Absolute Zero
|
the Temperature -273.15 C; given a value of zero on the Kelvin scale
|
|
|
Gay Lussacs Law
|
The pressure of a fixed mass of gas at constant volume varies directly with the Kelvin Temperature
|
|
|
Combined Gas Law
|
expresses the relationship between pressure, volume, and temperature of a fixed amount of gas
