Instead of the precise value of the kinetic energy of a system, for example a gas, it is generally more useful to consider its average kinetic energy, since it is absolutely impossible to measure the velocities of all the molecules: <E_k>=1/2 m<v^2>, where <> denotes the mean of the quantity in brackets. More importantly, the average kinetic energy has a very important physical interpretation: it is proportional to the temperature of the system. Temperature itself can be defined as a measure of the kinetic component of the internal energy of a system: according to the equipartition theorem, each independent quadratic energy term corresponds to an average energy of 1/2 kT, where k is Boltzmann's constant; so, in three dimensions the mean kinetic energy of a molecule is 3/2 kT.
The kinetic energy of a substance is the average kinetic energy of its particles.
No. Molecules have the lowest average kinetic energy in a solid. Plasma is the highest average kinetic energy.
Temperature is the average kinetic energy
Temperature refers to the average kinetic energy of a suubstance. The higher the average kinetic energy, the higher the temperature.
Average Kinetic Energy is determined by the temperate of the gas. The higher the temperature, the higher the average kinetic energy of the gas molecules.Total Kinetic Energy is the average kinetic energy multiplied by the mass - the number of gas molecules in the box.- DENNIS LAM
