Compressibility

measure of how much volume of matter decreases under pressure

what affects gas

volume, pressure, temperature

Boyle's law

for a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure

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

PV= nRT

Ideal gas constant

8.31

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

at constant volume and temperature, the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases

diffusion

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

effusion

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
