Unit 4: Gases
Term | Definition |
---|---|
Pressure | force exerted on a mass per unit of surface area |
Manometer | Device used to measure pressure by comparing the pressure of the gas in the tube to the pressure coming into the tube |
Boyle`s Law | at constant temperature,pressure and volume are inversely proportional |
Charles Law | at constant pressure, volume is directly proportional to temperature |
Guy Lussac`s Law | At constant volume, pressure is directly proportional to temperature |
Combined Gas Law | Boyle, Charle`s, and Guy-Lussac`s law to form on relationship |
Diffusion | movement of one substance through another |
Effusion | process by which gas escapes through small pores in materials |
Grahams Law of Diffusion | the rate of diffusion of a gas is inversely proportional to the square root of the mass of the gas |
Kinetic Molecular Theory | properties of an ideal gas |
Avagados Law | At the same temperature and pressure, equal volumes of any gas contain equal numbers of particles |
Mole | unit of measurement for the number of particles in a substance |
Dalton`s Law of Partial Pressure | the total pressure of the mixture is just the sum of all the partial pressures of the different gases in the mixture |
