Kinetic Theory Equations

Kinetic Theory is used to explain all the gas laws by observing the movement of the particles. Several assumptions are made to derive these equations:

Please tick the correct assumptions below.

(Hint: Use the Note entitled "4 Physics U1 M3 THE KINETIC THEORY OF GASES")

• The molecules of the gas can be assumed to be point molecules. This means that they have negligible volume.

• There is no intermolecular forces of attraction. The particles are in random motion and the average speed of the random motions produce a constant force (constant

  force → constant pressure)

• Collisions are (perfectly) elastic, the particles rebound after collision and kinetic energy is conserved.

• Impact time is minimum. The rate of change of momentum during the impact gives an average force provided that the time of impact is much less than the time

  between impacts.

• All molecules of a particular gas are identical.

• There is a sufficiently large number of molecules for statistics to be meaningfully

  applied.
