Gas Density
States of Matter & Gas Laws
g/L
The mass of a gas per unit volume, which for a gas depends strongly on temperature, pressure and molar mass.
ρ = pM / RT
Gaseous State
States of Matter & Gas Laws
Dimensionless
The state of matter in which particles are widely separated and move randomly at high speed, filling any container completely.
pV = nRT
Gay-Lussac's Pressure Law
States of Matter & Gas Laws
Pa/K
At constant volume, the pressure of a fixed mass of gas is directly proportional to its absolute temperature.
p₁ / T₁ = p₂ / T₂
Graham's Law of Diffusion
States of Matter & Gas Laws
Dimensionless
The rate at which a gas diffuses or effuses is inversely proportional to the square root of its molar mass.
r₁ / r₂ = √(M₂ / M₁)
