|---|---|---|---|---|---|
| Why are gases easier to compress than solids or liquids? | because gases are easily compressed due to the space between particles.
🗑
|
||||
| What is compressibility? | a measure of how much the volume decreases under pressure.
🗑
|
||||
| What does Boyle's law state? | for a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure.
🗑
|
||||
| How are the temperature and volume of a gas related? | as the temperature of an enclosed gas increases, the volume increased if the pressure is constant.
🗑
|
||||
| Charles's Law: | the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant.
🗑
|
||||
| Gay-Lussacs' Law: | the pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant.
🗑
|
||||
| Combined gas law: | a law that combines Boyle's, Charles's and Gay-Lussac's laws.
🗑
|
||||
| Ideal gas constant (R): | has the value 8.31 (L x Pa)(K x mol)
🗑
|
||||
| Ideal gas law: | P,V,T and n .
🗑
|
||||
| Partial pressure: | the contribution each gas in a mixture makes to the total pressure.
🗑
|
||||
| Dalton's law of partial pressures: | at constant volume and temperatures, the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases.
🗑
|
||||
| Diffusion: | the tendency of molecules to move towards areas of lower concentration until the concentration is uniform throughout.
🗑
|
||||
| Effusion: | 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 square root of the gas's molar mass.
🗑
