The table lists the specific latent heat of fusion for various metals. Because Kelvin is not a relative scale, unlike both of the major "degrees" scales. The molar heat of fusion is the amount of heat necessary to melt a mole of ice at its melting (or freezing) point. L f and L v are collectively called latent heat coefficients.They are latent, or hidden, because in phase changes, energy enters or leaves a system without causing a temperature change in the system; so, in effect, the energy is hidden. Latent Heat of Melting for some common Materials - Latent heat of fusion when changing between solid or liquid state for common materials like aluminum, ammonia, glycerin, water and more. Greater the heat of fusion of a substance higher the magnitude of intermolecular forces. The temperature stops increasing, and instead, the water vaporizes. In this experiment, an ice cube of mass mt, assumed to be at 0oC, is placed in a calorimeter . Example: Heating 2 kg water from -20 to 200C. Chemists and physicists define temperature as the average kinetic energy per molecule of a substance. 4.14: Calculating Heat of Reaction from Heat of Formation is shared under a CC BY-NC license and was authored, remixed, and/or curated by LibreTexts. Solution: We have, H f = 334 m = 12 Using the formula we get, Q = m H f = 334 (12) = 4008 J Problem 2. You can calculate the amount of heat energy needed to change a substances phase at its melting point using the following heat of fusion equation: q: Total change in heat energy (in Joules), Hf:Heat of fusion of substance (in Joules per gram).
