Ans: the amount of heat energy released or absorbed when a solid changing to liquid at atmospheric pressure at its melting point is known as the latent heat of. Heat of fusion-the amount of heat required to convert unit mass of a solid into the liquid without a d: water boils and absorbs latent heat of vaporization.

Heat of fusion is the energy needed for one gram of a solid to melt without any change in temperature heat of fusion is an important concept in chemistry. Heat of fusion and vaporization specific δh (j/g) substance, heat of fusion δh fus (j/g), heat of vaporization δhvap (j/g). Latent heat of fusion: the energy required to transition one unit of a substance from solid to liquid equivalently, the energy liberated when one unit of a substance. The latent heat involved in melting and solidification is called the latent heat of fusion (lhf), and that involved in boiling and condensation is called the latent.

The amount of heat energy absorbed by a solid substance to change it into the liquid without any rise in temperature is called latent heat of fusion the content of . The amount of heat required to convert one unit amount of substance from the as a consequence, the latent heat of fusion depends upon the crystal form of the . In the case of the latent heat of fusion it is the heat required to change a substance from a solid (ice) to a liquid (water) or vice versa while the latent heat of. Latent heat is thermal energy released or absorbed, by a body or a thermodynamic system, examples are latent heat of fusion and latent heat of vaporization involved in phase changes, ie a substance condensing or vaporizing at a. Heat of fusion is the amount of heat energy required to change the state of matter of a substance from a solid to a liquid it's also known as.

Specific heat: = energy required to change a unit mass of a material by 1°c units : energy per unit mass per degree latent heat = energy required to change the.
