What is the Kinetic Molecular Theory of Matter?
The Kinetic Molecular Theory of Matter is a concept that basically states that atoms and molecules possess an energy of motion (kinetic energy) that we perceive as temperature. In other words, atoms and molecules are constantly in motion , and we measure the energy of these movements as the temperature of that substance. This means if there is an increase in temperature, the atoms and molecules will gain more energy (kinetic energy) and move even faster. This kinetic-molecular theory states (postulates) that: • All matter (solid, liquid, and gas) is made up of tiny particles called atoms, or atoms that are joined to form molecules. • These particles are in constant motion. • Molecular motion is random. • Particles in motion possess kinetic energy. • Their motion increase as they gain energy. • There is an exchange (transfer) of energy between particles (atoms and molecules) during a collision between them. • Particles (molecules) in gases do not exert large forces on each other, unless
