As understood by the name itself, Archimedes’ principle was discovered by an ancient Greek mathematician who was also an inventor named Archimedes. He called Archimedes’ principle as a physical law of buoyancy.
In the field of chemistry, Le Chatelier’s principle is also known as the Equilibrium Law. It is helpful in predicting the effect of a change in conditions on the chemical equilibrium. This principle was named after Henry Louis Le Chatelier and Karl Ferdinand Braun.
In basic terms, pressure is defined as force per unit area. Given the force, the smaller the area, the more is the pressure applied, and vice versa.
Have you ever thought what causes the temperature change? What does air pressure mean or why it happens? Why do two gases diffuse very fast into each other? It’s because of the kinetic energy of the molecules present in gases.

All matter can move from one state to another. This is known as interconversion of the states of matter.
