measure of how much volume of matter decreases under pressure

what affects gas

volume, pressure, temperature

Boyle's law


Boyle's law

P x V = P x V

Charles's Law

the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant

Charles's Law

V/T = V/T

Gay-Lussac's Law

the pressure of a gias is directly proportional to the Kelvin temperature if the volume remains constant

Gay-Lussac's Law

P/T = P/T

Combined Gas law

descibes the relationship among the pressure, temperature, and volume of an enclosed gas

Combined Gas Law

PxV/T = PxV/T

Ideal Gas Law

used to calculate the number of moles of a contained gas

Ideal Gas Law


Ideal gas constant


Partial pressure

the contribution each gs in a mixture makes to the total pressure

partial pressure

Proom= P1 + P2 + P3...

Dalton's law of partial pressure



the tendency of molecules to move towards areas of lower concentration until concentration is uniform


a gas escapes through a tiny hole

Graham's law of effusion

the rate of effusion of a gas is inversely proportional to the square root of the gas's molar mass
