Temperature is directly proportional to the average kinetic energy of the molecules in a substance. If the degree of motion of the molecules inside an object doubles, the temperature will also double. More »

The kinetic energy of gas molecules is directly proportional to changes in temperature. When temperature increases, the kinetic energy of the gas molecules also increases; conversely, when the temperature decreases, the ... More »

The formula for average kinetic energy is one-half the mass times the square of the velocity. Using mathematical notation, the formula can be written as KE_avg = 1/2 x m x v^2, where KE_avg is the average kinetic energy,... More »

The average kinetic energy of the particles of a substance is determined by the temperature of the medium, using the equation for an ideal gas. If the temperature is unknown, then the average speed and mass of the partic... More »

The three main points of the kinetic theory of matter are all matter consists of molecules and atoms; these molecules and atoms are constantly in motion; and as the temperature increases, the speed of the particles, and ... More »

The difference between temperature and thermal energy is that temperature measures the average kinetic speed of molecules and thermal energy is the total kinetic energy of all particles in a given substance. In other wor... More »

The first assumption of the kinetic theory is that gas is made of identical molecules traveling in various directions. The second assumption is that the molecules do not lose energy when colliding with each other. The th... More »
