Gas Laws

Boyle’s Law

When temp remains constant, pressure and volume are proportional

Boyle’s Law equation

P1V1 = P2V2

Charles Law

If pressures constant, Temp and Volume are directly proportional

Charles Law Equation

V1/T1 = V2/T2

Gay-Lussac’s Law

When volumes constant, Pressure and Temp are proportional

Gay-Lussac’s Law equation

P1/T1 = P2/T2

Combined Gas Law equation

P1V1/T1 = P2V2/T2

Avogadro’s Law

When Pressure and Temperature are constant, Volume and Moles are proportional

Avogadro’s Law equation

V1/n1 = V2/n2

Density =

Molar mass / Mole Volume

Ideal Gas Law

A mathematical way to describe behavior of gas at set conditions

Gas Law equation

PV = nRT

Dalton’s Law

The total Pressure of a mixture of gasses = the sum of the Partial Pressures of its Component Gases

Kinetic Molecular Theory

-Gases consist of smaller particles

-Distance Between gas is large bc of gas small size

-Particles are rapid and random

-The average kinetic energy of particles depends only on the temperature of the gas

Volume at STP
