explain
A. allotropy.
B. Brownian movement.
C. diffusion.
D. Tyndal effect.
E. vaporization.

The correct answer is A. allotropy

Explanation: The Kinetic Theory of Gases is a model that helps us understand the behavior of gases. It explains various phenomena like Brownian movement, diffusion, the Tyndall effect, and vaporization. However, it cannot explain allotropy.
Allotropy refers to the existence of an element in two or more physical forms in the same physical state. It's a property of certain elements to exist in two or more different forms, in the same physical state. For instance, carbon can exist as diamond, graphite, and fullerene. Phosphorus can exist as black, white and red. Sulphur can exist as rhombic, monoclinic and amorphous. The differences in these forms are due to the difference in the arrangement of their atoms.

In contrast, the kinetic theory is about the behavior of particles (atoms, molecules, or ions) in a substance. 

This theory make the following assumptions;

1. that all matter is composed of tiny particles which are in constant random motion. 

2. The speed and direction of these particles depend on their temperature and pressure.

Take note that while the kinetic theory can explain several phenomena like Brownian movement (the random movement of particles in a fluid), diffusion (the process of spread of particles from high concentration to low concentration), the Tyndall effect (the scattering of light particles in a colloid or in a very fine suspension), and vaporization (the process where a liquid turns into a gas); it cannot explain allotropy which is based on the structural arrangement of atoms in an element, not their movement.
