Question

Fundamentally, pressure is defined as force per unit area. what is the source of the force in a gas sample?

Answer 1

The source of the force in the gas sample is; The force is composed of the sum of the collisions only between the gas molecules and the container

What is the relationship between Force and Pressure?

We are given that;

Pressure = Force /Area

Now, for any gas sample, force is defined as basically the force exerted by the gas molecules when they strike the surface and bounce back inside the container where they are located.

Now, from the definition above we can conclude that the source of the force in the gas sample will be The force is composed of the sum of the collisions only between the gas molecules and the container
