Sensible heat is associated with a change in temperature of a substance, whereas latent heat is associated with a phase change of a substance without a change in temperature. For example, when water is heated from 20°C to 80°C, the heat added is sensible heat because the temperature of the water increases. However, when water is heated from 100°C to 110°C and it changes from a liquid to a gas, the heat added is latent heat because the temperature remains constant during the phase change.
