∴ Latent heat = Mass × Specific latent heat Specific latent heat of fusionis defined as the amount of heat required to change a unit mass of a solid at its melting point into a liquid, without changing its temperature. Specific latent heat of vaporizationis defined as the amount of heat ...
latent heat of fusion(Δhf): heat required to melt a solid; and (iii) latent heat of sublimation(Δhs): heat required to directly vaporise a solid. Condensationofgas to liquidrequires removal rather than addition of heat; the latent heat evolved in condensation is −Δhv. Similarly, the...
While latent heat of fusion and vaporization are used in physics and chemistry, meteorologists also consider sensible heat. When latent heat is absorbed or released, it produces instability in the atmosphere, potentially producing severe weather. The change in latent heat alters the temperature of obj...
A peak in the latent heats and entropies of fusion, which is centred on the point of intersection of the f.c.t. to f.c.c. phase-boundary line with the melting curve has been observed in both the In-Tl and In-Cd binary alloy systems. The difference between contributions of the soft...
latent heat 1.The quantity of heat which is absorbed or released by a substance during a change of state (fusion or vaporization) at constant temperature. 2.Heat released or absorbed when a substance changes state without a change in temperature. ...
