Respuesta :
you can know which one has more thermal energy by testing the temperature, if it is warmer the more energy it has because the particles are going faster than they would if it was cold. because, when its cold the particles slow down until they are so cold they are frozen. (ice).
According to my school book thermal energy is the total kinetic energy of the particles that make up a substance thermal energy is measured in joules know that this is different from the temperature for it is the average kinetic energy while the thermal energy is the total kinetic energy.not done answering this
