Question

The_ explain how particles act when their spacing and movements change

Answer 1

Answer:The KINETIC MOLECULAR THEORY explains how particles act when their spacing and movement change.

Explanation:

Answer 2

How particles act when their spacing and movements change is explained by kinetic molecular theory. It states that:

• The molecules are in constant random motion as a result they collide with each other and also with the walls of the container.
• Due to colliding the particles impart some momentum to the walls.
• As a result there is production of a force that is measurable and if you divide this force by area it is termed as pressure.
• Actually the particles never slow down and remain at the same speed.
