Types of gas laws and equations

What number do you add to convert C to K

273

Boyle's Law

Pressure and volume are inversely proportional at a constant temperature and amount of gas. When volume goes up, pressure goes down.

P1V1 = P2V2

Hint to remember:

boyles law like boils at high pressure/volume

Charles's Law

Volume and temperature are directly proportional at a constant pressure and amount of gas. When temperature goes up, volume expands. Temperature must always be in Kelvin

V1/T1 = V2/T2

Hint to rember:

Charles likes to watch TV but in reverse = V1/T1

Gay-Lussac's Law (Amontons's Law):

Pressure and temperature are directly proportional at a constant volume and amount of gas. When temperature goes up, pressure increases.

P1/T1 = P2/T2

Hint to rember:

P/T like part - theres a dash in his name

Avogadro's Law:

Volume and the number of moles are directly proportional at a constant pressure and temperatureAdding more gas increases the volume.

V1/n1 = V2/n2

Hint to remember

Avogadro’s ewuation uses moles unlike the others

Combined Gas Law

P1V1 /T2 = P2V2/ T2

Key to rember:

P x V

Pressure and volume allways times, When theres a T its allways on the bottom and divide

Ideal Gas Law

PV = nRT

𝟎.𝟎𝟖𝟐𝟎𝟔L x atm / (mol x k)
