The latent heat of fusion, also known as the enthalpy of fusion, is the energy required to change a substance from a liquid to a solid state. In the case of water, the process of freezing is endothermic, meaning it absorbs heat from the surroundings, while melting is exothermic, releasing heat. This duality explains why heat is necessary for freezing, as the energy exchange maintains thermal equilibrium. Understanding these principles is crucial for accurately measuring and interpreting phase changes in substances.

MadmanMurray said:I did a lab experiment were we measured the latent heat of fusion of ice but I am not quite sure what that is. I read that latent heat of fusion is the energy(heat) it takes to change liquid to solid. Is that true? Why would it take heat to freeze something?
