IB Physics When is a real gas most like an ideal gas?
/A common question is the departure of the behaviour of a real gas from ideal gas behaviour. A tutorial sheet on this concept follows.
- Can an ideal gas be liquefied?
- Do the particles of an ideal gas collide with each other?
- The thermodynamic temperature of an ideal gas is increased. How does this affect the collision frequency of the particles?
- At which temperature, high or low, are the particles of an ideal gas more likely to be in the vicinity of each other?
- At which pressure, high or low, are the particles of an ideal gas more likely to be in the near vicinity of each other?
- For an ideal gas pV/nT has a constant value for all values of p, V and T. Sketch a graph showing pV/nT versus p for oxygen gas.
