Final answer:
Temperature is the measure of average kinetic energy of particles. Thermal energy transfers from a hotter object to a cooler one, resulting in a change in temperature.
Step-by-step explanation:
Temperature is defined as the measure of the average kinetic energy of the particles in a substance. Thermal energy, on the other hand, refers to the total potential and kinetic energy of all the particles in a substance. When two objects at different temperatures come into contact, the thermal energy from the hotter object transfers to the cooler object, resulting in a transfer of thermal energy and a change in temperature.
