|---|---|---|---|---|---|
| Avogadro's Hypothesis | Equal volumes of gases at the same temperature and pressure contain equal numbers of particles.
🗑
|
||||
| Boyle's Law | For a fixed mass of gas atconstanttemperature, the volume of the gas varies inversely with pressure.
🗑
|
||||
| Charles's Law | The volume of a fixed mass of gas is directly proportionalto its Kelvin temperature if the pressure is kept constant.
🗑
|
||||
| Combined Gas Law | A relationship describing the behaviorof gases that combines Boyle's law, Charles' law, and GayLussac's law.
🗑
|
||||
| Dalton's Law of Partial Pressures | At constant volume and temperature, the total presure ofa mixture of gases is the sum of the partial pressuresof all the gases present.
🗑
|
||||
| Diffusion | The tendency of molecules and ions to move toward areas of lower concentration until the concentration is uniform througout the system.
🗑
|
||||
| Effusion | A process that occurs when a gas escapes through a tiny hole in its container.
🗑
|
||||
| Graham's Law of effusion | The rate of effusion of a gas is inversely proportional to the squareroot of its formula mass; this relationship is also true for the diffusion of gases.
🗑
|
||||
| Ideal Gas Constant | A term in the ideal gas law, which has the valuse 8.31 (LxkPa)/(Kxmol)
🗑
|
||||
| Ideal Gas Law | The relationship PxV=nxRxT, which descrives the behavior of an ideal gas.
🗑
|
||||
| Partial Pressure | The pressure exerted by each gas in a gaseous mixture.
