Answer
According to the particle model, gases exert pressure on the walls of their containers due to the constant collisions of gas particles against those walls, caused by the particles' rapid, unrestricted motion within large inter-particulate distances.
Explanation
## Step1: We will use the particle model, or the Kinetic Molecular Theory, which suggests certain qualities of ideal gas particles should be noted.## Step2:The Key qualities of ideal gases from the theory argument are: Therefore, First, gas molecules are far apart from each other. This far distance allows the gas particles to move uncontrolled and uninterruptedly. ## Step3:Secondly, The gas particles move at high speed and in all possible directions as unrestricted by containment.## Step 4:Finally, gas particles constantly interact with the container's walls due to their high speed and uncontrolled motion. These collisions force9 a reaction against the boundaries of the gas’s container; this reaction is the pressure exerted by the gas on the container's walls.
