Is the Kinetic theory of matter same for all states of matter? If so, then in the chapter More About Solids Liquids and gases, why does it mention the points of the kinetic theory as Kinetic Theory of Gases?

You should study the kinetic theory for all states of matter.This theory explains the differences between the three states of matter. It states that all matter is made up of moving particles which are molecules or atoms.

In solids, the particles are so tightly bound to each another that they can only vibrate but not move to another location. 

In liquids, the particles have enough free space to move about, but they still attract one another. 

In gases, the particles are far apart and can move about freely since there is much free space.


Solids change into liquids, and liquids into gases, when the particles gain more kinetic energy, like when being heated. 

Particles move in a straight line between collisions and are able to move apart from one another. When the molecules vibrate more quickly upon heating, some of it escapes from the matter. This is what the Kinetic Theory is about.

Hope this helps.
