Term
Kinetic-molecular theory
Definition
the idea that particles of matter are always in motion
Term
ideal gas
Definition
an imaginary gas that perfectly fits all the assumptions of the kinetic-molecular theory
Term
elastic collision
Definition
one in which there is no net loss of kinetic energy
Term
fluid
Definition
the flow of liquids and gases
Term
diffusion
Definition
spontaneous mixing of the particles of two substances caused by their random motion
Term
effusion
Definition
a process by which gas particles pass through a tiny opening
Term
real gas
Definition
a gas that does not behave to the assumptions of the kinetic-molecular theory
Term
pressure
Definition
the force per unit area on a surface
Term
newton(N)
Definition
the force that will increase the speed of a one kilogram mass by one meter per second each second it is applied

Term
standard temperature and pressure(STP)
Definition
for purposes of comparision standard conditions of exactly 1 atm and 0 degrees
Term
gas laws
Definition
simple mathematical relationships between the volume, temperture, pressure,and the amount of a gas
Term
boyle's law
Definition
states the volume that the volume of a fixed mass of gas varies inversely with the pressure at cconstant temperture
Term
absolute zero
Definition
the temperture -273.15degrees
Term
charles's law
Definition
the volume of a fixedmass of gas at constant pressure varies directly with the kelvin temperture
Term
barometer
Definition
a device used to measure atmospheric pressure
Term
gay-lussac's law
Definition
pressure of a fixed mass of a gas at constant volume varies directly with the kelvin temperture
Term
combined gas law
Definition
the relationship between pressure, volume, and temperture of a fixed amount of gas
Term
partial pressure
Definition
pressure of gas in each mixture
Term
daltons law of partial pressures
Definition
the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
