The sentence that describes the average kinetic energy of the particles is - the sum of the particles kinetic energies divided by 1000.
It is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The kind of motion may be translation (or motion along a path from one place to another), rotation about an axis, vibration, or any combination of motions.
When temperature increases, the kinetic energy of the gas molecules also increases; conversely, when the temperature decreases, the gas molecules' kinetic energy also decreases. As the temperature of a system increases, the molecules within it begin to move faster, and the velocity of the particles is directly proportional to the kinetic energy.
Thus, the sentence that describes the average kinetic energy of the particles is - the sum of the particles kinetic energies divided by 1000.
