Question

What is KMT and what are its assumptions?

Answer 1

Definition

KMT stands for kinetic molecular theory of gases. It defines how gaseous materials behave.

It accomplishes so by explaining the macroscopic activity as well as attributes of gaseous substances utilizing the tiny constituents of gaseous elements.

Assumptions of KMT

1. All gaseous substances have been composed of multiple gaseous particles with no specified volume but a known mass. In plenty of other circumstances, as compared to the general population distance between two particles, the overall volume filled by a gaseous component is minimal.
2. The components that make up gases have always been in continual movement.
3. Collisions involving two or maybe more gaseous molecules always seem to be completely elastic.
4. The average value of such a gaseous particle's kinetic energy is across all gases. The average kinetic energy of such a gas would be directly proportional to their absolute temperatures.
5. Intermolecular forces don't exist between the particles of gaseous material. As a result, the gaseous particle's total amount of energy is equivalent to its kinetic energy.

Therefore, this theory explains the different macroscopic features of gas through considerations of the microscopic nature of such atoms as well as molecules that make up the gas.
