When is latent heat of fusion used

Compilations of experimental results of DHSL are available for a number of materials [Weast ], but there is no reliable means of their estimation [Reid et al.

Weast, R. Boca Raton, FL. Reid, R. Consequently the level B moves up and the level A which can be in a quite narrow capillary tube goes down, so the reduction in volume and hence the mass of ice melted can be determined quite accurately.

Thus the latent heat of fusion of ice can be determined. Once the equipment has been calibrated i. It will be understood, I think, that, in using the apparatus to measure the specific latent heat of ice, it is necessary to know the densities of ice and of water precisely.

Atomic weight is the average mass of all the isotopes of an element. Force is not involved.

As its name suggests, it transfers heat from high temperature regions to lower temperature regions where there is more space for heat sinks or cooling fans.

Although it just looks like a sealed metal pipe, there is a wick or porous material and a liquid with a high latent heat of vaporisation.

When the pipe is heated the liquid uses the heat to evaporate and changes into a gas, the gas moves to a colder region of the heat pipe where is condenses and uses the latent heat to change back into a liquid. Heat pipes are a reliable and cost effective solution for laptop computers where fans would reduce battery life. Do you have any Physics Questions?
