Gas Laws & KMT (Pat)

Dalton’s Law of Partial Pressures (definition)

Within a mixture of gases, each gas applies their own partial pressure adding to the total pressure

Dalton’s Law of Partial Pressures (formula)

Ptotal= P1 + P2 + …

Boyle’s Law (definition)

At constant temperature and quantity, Pressure and Volume are inversely proportional

Boyle’s Law (equation)

P1 * V1 = P2 * V2

Charles’ Law (definition)

At constant pressure and quantity, Volume and Temperature are proportional

Charles’ Law (equation)

V1 / T1 = V2 / T2

Gay-Lussac’s Law (definition)

At constant volume and quantity, Pressure and Temperature are proportional.

Gay-Lussac’s Law (equation)

P1 / T1 = P2 / T2

Avogadro’s Law (definition)

At constant temperature and pressure, Moles (n) is proportional to Volume

Avogadro’s Law (equation)

V1 / n1 = V2 / n2

Combined Gas Law (definition)

Combines all three previous laws into one comprehensive “combined” equation. pressure, volume, and temperature all change

Combined Gas Law (equation)

P1*V1 / n1*T1 = P2*V2 / n2*T2

Ideal Gas Law (definition)

The “state” of the gas based on its current pressure, volume, quantity/moles, and temperature

Ideal Gas Law (equation)

PV=nRT
