kinetic theory (redirected from Kinetic-molecular theory)

kinetic theory

n.

A theory concerning the thermodynamic behavior of matter, especially the relationships among pressure, volume, and temperature in gases. It is based on the dependence of temperature on the kinetic energy of the rapidly moving particles of a substance. According to the theory, energy and momentum are conserved in all collisions between particles, and the average behavior of the particles can be deduced by statistical analysis.

kinetic theory

A fundamental theory of matter that explains physical properties in terms of the motion of atoms and molecules. In kinetic theory, properties such as pressure and temperature are viewed as statistical properties of the overall behavior of large numbers of particles. For example, the pressure exerted by a gas on an object is the net result of the numerous collisions of the gas molecules against the object.
