| elastic collision | a collision between gas particles and container walls in which there are no net loss of kinetic energy.
🗑
|
||||
| fluid | a substance that can flow and therefore take the shape of its container; a liquid or a gas.
🗑
|

| Kelvin | equal to 273.15 + oC.
🗑
|
||||
| Boyle’s Law | states that the volume of a fixed mass of gas varies inversely with the pressure at constant temperature.
🗑
|
||||
| Charles’s Law | the volume of a fixed mass of gas at constant pressure varies directly with the Kelvin temperature.
🗑
|
||||
| Combined gas law | the relationship between the pressure, volume, and temperature of a fixed amount of gas.
🗑
|
||||
| Dalton’s Law of partial pressure | the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases.
🗑
|
||||
| Gay-Lusscac’s Law | the pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature.
🗑
|
||||
| Ideal gas law | the mathematical relationship of pressure, volume, temperature, and the number of moles of gas.
🗑
|
