Question

Kinetic theory of matter states about :

• A. three states of matter
• B. differences between the three states of matter
• C. fourth state of matter
• D. all of the above

Answer 1

The correct option is B differences between the three states of matter

The kinetic 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 other 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,

So, the correct option is $B$
