Gas laws

Gas law study terms

Gas

A state of matter with no definite shape or volume

thermal energy

The total energy of motion in the particles of a substance

kinetic molecular theory

all matter consists of tiny particles that are in constant motion

Boyles law

A principle that describes the relationship between the pressure and volume of a gas at constant temperature

Boyle's Equation

P1V1=P2V2

Charles law

the law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature of the gas increases and the volume of the gas decreases as the temperature of the gas decreases

Charles equation

V1/T1=V2/T2

Gay-Lussac's Law

the pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant

Gay-Lussac's Equation

P1/T1=P2/T2

direct relationship

one variable increases with an increase in another variable

inverse relationship

one variable decreases when another variable increases

units of gas pressure

1 atm = 101.3 kPa = 760mm Hg

Kelvin

The SI base unit of temperature based on absolute zero (no negative numbers)

22.4 L

Volume of one mole of gas at STP

STP

standard temperature and pressure
