1.5 - Ideal Gases Flashcards
1
Q
What is an ideal gas?
A
An ideal gas is a hypothetical gas that obeys the gas laws and the kinetic-molecular theory, that is:
- Particles are in constant, random, straight line motion
- Collisions are elastic
- Occupied volume is negligible to the container volume
- there are no intermolecular forces
- Ek is directly proportional to absolute temperature
2
Q
Under what conditions to real gasses approximate to ideal gases?
A
High temperature and low pressure.
3
Q
What is the molar volume?
A
The volume occupied by one mole of an ideal gas; 22.7 dm^3.
