Answer:
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.
