Heat of fusion and heat of vaporization by debbie mcclinton dr. miriam douglass dr. martin mcclinton. learners examine graphs and read that the heat of fusion is the heat energy absorbed by one mole of solid as it is converted to liquid, while the heat of vaporization is the heat energy absorbed by one mole of liquid as it is converted to gas. The heat of vaporization of a liquid is the energy it takes for the substance to transform into a gas. as energy is added to a system, the bonds in the liquid gain energy and reach a point where they can break and undergo a phase change, signified by Δh fus . Leave questions in the comments and i'll generally get to them!. Latent heat of vaporization: the "amount of heat" needed to convert "unit mass of liquid" into its "vapour state" without change in its temperature is known as "latent heat of vaporization". example: the " latent heat of vaporization " of water is "540 cal g °c". Heat of fusion is the amount of heat required to turn one unit mass of a solid to one unit mass of liquid without change in temperature. e.g. to melt one gram of 0 degree c ice to 1 gram water at 0 degree c; 80 calories of heat is required. so the heat of fusion of ice is 80 calorie per gram of ice.

Latent heat is the heat absorbed or released as the result of a phase change. this temperature change during a phase change is due to the energy released from the potential energy stored in the bonds between the particles, and not due to the energy release from the kinetic energy of the particle. Latent heat of fusion. in case of solid to liquid phase change, the change in enthalpy required to change its state is known as the enthalpy of fusion, (symbol ∆h fus; unit: j) also known as the (latent) heat of fusion. latent heat is the amount of heat added to or removed from a substance to produce a change in phase. Next, determine the total heat required to melt the solid. after an experiment to melt the solid, it’s determined that the total heat added to the solid was 4000j. finally, calculate the heat of fusion. using the formula we find the heat of fusion to be 4000j 50g = 80j g.
