Boyle's Law

Temp Constant

P1V1 = P2V2

Charles Law

Pressure Constant

V1/T1 = V2/T2

Amonton's Law

Volume Constant

P1/T1 = P2/T2

Avogadro's Law

Temp and Pressure Constant

V1/n1 = V1/n2

Combined Gas Law

P1V1/n1T1 = P2V2/n2T2

R = ?

0.08206 (L)(atm/K)(mole)

STP

Standard Temp and Pressure

What is STP?

Pressure = 1atm

Temp = 0 degrees celcius, 273 kelvin

Dalton's Law

Partial Pressures

P(total) = P1 + P2 + P3 + ...

Kinetic Molecular Theory (KMT)

Average Energy is proportional to the gas temp

Diffusion

Mixing of gases, evenly dispersed, something moves from an area of higher concentration to an area of lower concentration to reach equilibrium

Effusion

Selective mixing of gases, slower dispersed, gas moves through small hole

Ideal Gas

Tiny molecules

Always in rapid motion

No attraction to each other

Experience collisions, but no loss of kinetic energy

Kinetic energy proportional to temp

Real Gas

Tiny molecules

Always in rapid motion, occupy volume

Attraction to other gas molecules

Kinetic energy proportional to temp

Gases closest to ideal when...

Low pressures and high temps

Standard Gas Pressure

1atm
