How does latent heat show up on phase diagram
WebHeat of fusion, also called enthalpy of fusion or latent heat of fusion, is a quantity of energy needed to melt or freeze a substance under conditions of constant pressure. When studying chemistry, “fusion” simply has the same definition as melting. In the classroom, you mostly use heat of fusion when a substance is at its melting point or ... Weblatent heat, or sometimes, a heat of transformation; we will say more about them later on. For now, note that when a pot of water boils, what happens is that the heat from the burner is absorbed by liquid water; as it absorbs the latent heat, the water is transformed into vapor (bubbles), which rise to the top and disperse. This process takes ...
