What is the formula for Boyles law
P V = P V
1 1 2 2
States that the volume of a fixed mass of gas varied inversely with the pressure at constant temperature
Boyles law
What is held constant in Boyles law
Temperature
States that the volume of a fixed mass of gas at constant pressure varies directly with the Kelvin temperature
Charles law
What is the formula for Charles law
V1 V2
—- = —–
T1 T2
What is held constant in Charles law
Pressure
States that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules
Avogadro’s law
What is the formula for Avogadro’s law
n1 n2
—- = —-
v1 v2
What is held constant for Avogadro’s law
Temperature and pressure
What is the formula for the combined gas law
P1 V1 P2 V2
——- = ——–
T1 T2
What does the combined gas law do
It expresses the relationship between pressure volume and temperature of a fixed amount of gas
What is the formula for the ideal gas law
PV = nRT
What is the value in units of R in the ideal gas law
R = .0821 L • atm / mole • K
The random movement of gases from an area of higher concentration to an area of lower concentration in open space
Diffusion
The random movement of gases from an area of higher concentration to an area of lower concentration through a small hole or opening in the container
Effusion
