Ideal Gas

A theoretical gas composed of a set of randomly-moving particles. At conditions such as STP, most real gases behave like an ideal gas.

Combined Gas Law (Definition)

At constant amount of gas, there is a predictable relationship between temperature, pressure, and volume

Charles' Law (Definition)

At constant pressure and amount of gas, temperature is directly related to volume (as one rises the other risess).

Boyle's Law (Definition)

At constant temperature and amount of gas, pressure and volume are inversely related (as one rises the other falls).

Ideal Gas Law (Definition)

Describes the relationship between the pressure, volume, temperature, and number of moles for a sample of gas. (The Ideal Gas Law is derived from the Combined Gas Law and Avogadro's Principle.)

Kinetic Molecular Theory

Matter is made up of atoms which are in continual random motion which is related to temperature

Combined Gas Law (Equation)

P1V1/T1=P2V2/T2

Boyle's Law (Equation)

P1V1=P2V2

The Ideal Gas Law (Equation)

PV=nRT

.0821atm-L/mol-K

R (atm)

STP

Standard Temperature and Pressure. 273 Kelvin (0 Celsius), 1 atmosphere (760 torr, 760 kPA).

absolute zero

The coldest temperature, 0 Kelvin, that can be reached. It is the hypothetical temperature at which all molecular motion stops.

Charles' Law (Equation)

V1/T1=V2/T2

universal gas constant

constant that relates pressure, volume, temperature and number of moles of gas in an ideal gas law, .0821 (L x atm)/(K x mol)

mm Hg

millimeters of mercury (1 atm = 760 mm Hg)
