Boyle’s Law

at constant “T” temperature, the volume of gas is inversely proportional

Boyle's Law Formula

P1V1 = P2V2

Charle’s Law

At constant “P“ pressure, the volume of gas is directly proportional to temp (K)

Charle’s Law Formula

V1/T1 = V2/T2

Gay Lussac’s Law

At constant “V“ volume, the pressure of gas is directly proportional to temperature

Gay Lussac’s Formula

P1/T1 = P2/T2

Combined Gas Law

has NO actual law only a formula

• no graph

Combined Gas Law Formula

P1V1 / T1 = P2V2 / T2

Combined Gas Law calculations

• STP (Standard temp, pressure) = (0°C, 1 atm)

• RTP (Room temp, pressure) = (25°C, 1 atm)

Arrogandro’s Law

At constant ““T and “P“, volume is directly proportional to n

• n = # moles of gas

Arrogandro’s Law Formula

V1/n1 = V2/n2

• linear graph

Ideal Gas Law

“P“ and “V“ are inversely proportional, while “V“ and “T“ (and n (moles) are directly proportional

Ideal Gas Law Formula

PV=nRT

• R = 0.0821L*atm / k*mole
