### 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

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

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

P/T = P/T

### Combined Gas law

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

PxV/T = PxV/T

### Ideal Gas Law

used to calculate the number of moles of a contained gas

PV= nRT

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
