Question

The kinetic particle theory explains the:
(A) Properties of the different states of matter
(B) Size and rigidity of different states of matter
(C) Reaction of matter
(D) All of the above

Answer 1

Kinetic particle theory is also known as the kinetic theory of particles. It involves the way the particles (atoms, molecules or ions) forming the matter moves in the space.

Complete step by step solution:
We will know some details about the kinetic particle theory.
-Kinetic particle theory states that all the particles of the matter are in continuous motion or they are constantly moving. The energy of the particles has an effect on the velocity of the particles and it decides the state of the matter.
-The particles here may be atoms, molecules or ions.
-The particle theory helps to explain certain properties of the matter and it enables us to visualize us to see or predict what is happening at the very small scales.
-We know that in solids, the particles are held tightly and they cannot move freely through space. So, their movement is very limited and they can just vibrate around its position.
-In liquids, the particles are far as compared with the solids and they are able to move freely in all directions. However, in gases, the particles are in rapid motion and can move freely throughout the vessel.
Thus, we can say that kinetic particle theory explains the properties of different states of matter.

Therefore, the correct answer is (A).

Note: Note that the kinetic particle theory does not have any relation with the rigidity or the volume (size) of the matter. So, do not get confused about that. Kinetic particle theory just explains the way particles move in space, so it cannot explain the reactivity of the particles.
