Know these basic assumptions of the Kinetic-Molecular Theory.Kinetic-Molecular Theory
By indirect observations, the Kinetic-Molecular Theory has been arrived at to
explain the forces between molecules and the energy the molecules possess.
There are three basic assumptions to the Kinetic-Molecular Theory:
- Matter in all its forms (solid, liquid, and gas) is composed of extremely
small particles. In many cases these are called molecules. The space
occupied by the gas particles themselves is ignored in comparison with the
volume of the space in which they are contained. - The particles of matter are in constant motion. In solids, this motion is
restricted to a small space. In liquids, the particles have a more random
pattern but still are restricted to a kind of rolling over one another. In a gas,
the particles are in continuous, random, straight-line motion. - When these particles collide with each other or with the walls of the
container, there is no loss of energy.
