Modern theory have proposed a variety of mechanisms for cooling other than blackbody radiation, including nuclear decay heating and latent heat of fusion from liquid-to-solid crystallization.
22.
Based on the heat of fusion for water being 144 Btu per pound, 1 ton of refrigeration = 12, 000 Btu / h = 12, 660 kJ / h =.
23.
There are distinct differences between crystalline solids and amorphous solids : most notably, the process of forming a glass does not release the latent heat of fusion, but forming a crystal does.
24.
TES is practical because of water's large heat of fusion : the melting of one metric ton of ice ( approximately one cubic metre in size ) can capture of thermal energy.
25.
They also made a study of the latent heat of fusion of ice, and a careful investigation of the range of applicability of the Dulong-Petit law representing the law of cooling.
26.
:: The thermal " cost " of eating ice includes the latent heat of fusion ( i . e . the energy required to melt the ice ) in addition to the thermal capacity.
27.
This method assumes that the heat of fusion is temperature-independent, ignores additional transition temperatures between different solid phases, and it gives a fair estimation for temperatures not too far from the melting point.
28.
The thermal conductivity of ice is very low compared with that of metals, and water releases of latent heat of fusion as it freezes, defeating rapid cooldown in specimens more than a few micrometres thick.
29.
One method is to estimate the sublimation pressure from extrapolated liquid vapor pressures ( of the supercooled liquid ), if the heat of fusion is known, by using this particular form of the Clausius Clapeyron relation:
30.
The melting ice still has to pay the heat of fusion cost, and the only place to take that energy from is the heat energy . talk ) 11 : 26, 2 February 2011 ( UTC)
