Avagadros principal?
For all gases at constant temp and pressure , the number of moles of gas will be directly proportional to the volume. So ALL gases having the SAME volume will have the SAME number of moles
Under stp conditions , one mole of ideal gas has a volume of ___
22.4L
Density?
Mass/volume
At moderate high pressure , volume of gas is _____
At high pressure , volume of gas is ___
Lesser than expected
Higher than expected
As the temperature decreases the volume seems ____
To be Smaller than ideal
What are the 5 assumptions of kinetic molecular theory
1) gas particles volumes are negligible compared to their container volume
2) gas molecules are inert
3) continuous random motion and collisions
4) elastic collisions (no gain or loss of energy )
5) the average kinetic energy of gas particles are proportional to the absolute temperature and is the same for all gases at a given temperature
What does the maxwell Boltzmann curve show ?
The distribution of speeds of gas particles at a given temperature
The rates at which two gases diffuse are ______ proportional to the _______
Inversely
Square root of their molar masses
The flow of gas particles under pressure from one compartment to another through a small hole
Effusion
For two gases at the same temperature , the rates of effusion are proportional to the ______
Average speeds
What are the conditions for an ideal gas ?
High temperature
Low pressure
All gases will have the same number of moles in the same volume at a ___ temperature and pressure
Constant
