Homework Questions
1. What would happen to the gas if the molecular collisions are not elastic?
2. Differentiate between total K.E. and translational kinetic energy. For what type of molecules, the two
are equal?
3.
Write the Postulates of KTG.
4. Point out two postulates of KTG which are the causes of deviation from ideal behaviour.
Solutions
1. On every collision, there would have been loss of energy. As a result, the molecules would have flowed
down and ultimately settled down in the vessel moreover, the pressure would have gradually reduced
to zero
2. Total kinetic energy is the sum of translational, vibrational and relational kinetic energies. The total
kinetic energy is equal to the translational kinetic energy for mono atomic gases as they do not
possess vibrational relational motion but only have translations motions
