Distinguish between temperature and thermal energy

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. Convection occurs when energy is transferred while the mass of a substance moves. The temperature is measured in Celsius, Kelvin, and Fahrenheit. The temperature does not depend on the quantity of the substance - it is related to the average kinetic energy of the particles. The thermal energy depends on the quantity of the substance - it is related to the total kinetic energy of the particles.
