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
