How does latent heat work
WebWhen a system absorbs or loses heat, the average kinetic energy of the molecules will change. Thus, heat transfer results in a change in the system's temperature as long as the … WebThe latent heat associated with melting is called the latent heat of fusion. If enough energy is removed for the liquid water to be converted back into ice during freezing, the latent heat stored in the water molecules is released back into the surroundings as heat (also called latent heat of fusion).
