Boyl's Law (formula)
Gay-Lussac's Law (formula)
P1 / T1 = P2 / T2
Combined Gas Law (formula)
P1V1 / T1 = P2V2 / T2
Ideal Gas Equation (formula)
PV = nRT
Dalton's Law of Partial Pressure (formula)
Ptotal = P1+P2+P3+...
Universal Gas Constant (R)
0.082 Liter-atmostphere / mole-Kelvin
Boyl's Law (definition)
For a given quantity of gas at a constant temperature, the volume of a gas is inversely proportionate to its pressure
Charles' Law (definition)
for a given quantity of gas at a constant pressure, the volume of gas is directly proportional to it's absolute temperature.
Gay-Lussac's Law (definition)
For a given quantity of gas at a constant volume, the pressure is directly related to the absolute temperature
Dalton's Law of Partial Pressure (definition)
the pressure exterted by an individual gas in a mixture, if it alone occupies the sam volume as the mixture
P = force / area
atm - mmHg
1 atm = 760 mm Hg
atm - Torr
1 atm = 760 Torr
atm - psi
1 atm = 14.7 psi
atm - Pascals
1 atm = 101,325 Pa
Kinetic Theory of Gases
- 1. made of small particles, in straight lines in all directions.
- 2. posess KE. Temp of gas is average KE
- 3. collisions are perfectly elastic
- 4. exert pressure on container due to collisions with walls
- 5. volume of gas is tiny compared to volume occupied
Standard temperature and pressure consists of 1.00 atm, 0 degrees Celcius and 22.4L/1 mol of any gas.
