鋁的比熱容為0.88×103 J/(kg·℃)，熔點(diǎn)為660.37。鋁的熔化熱為3.98×105J/kg，鋁的蒸發(fā)熱為1.05×107J/kg。熔化熱:單位質(zhì)量晶體物質(zhì)在熔點(diǎn)從固相到液相吸收的相變潛熱。晶體的熔化是粒子由規(guī)則排列變?yōu)椴灰?guī)則排列的過(guò)程。
　　The specific heat capacity and melting point of aluminium are 0.88 *103 J/(kg * C) and 660.37 respectively. The melting heat of aluminium is 3.98 x 105J/kg and the evaporation heat of aluminium is 1.05 x 107J/kg. Melting heat: Latent heat of phase transition absorbed by crystalline substances per unit mass at melting point from solid phase to liquid phase. The melting of crystals is a process in which particles are arranged irregularly instead of regularly.
　　這些熱量將用于對(duì)分子引力,分子勢(shì)能增加,也就是說(shuō),吸收的熱量材料所需要的能量破壞晶格結(jié)構(gòu),使分子運(yùn)動(dòng)狀態(tài)改變質(zhì)變的固體分子熱運(yùn)動(dòng)的液體分子熱運(yùn)動(dòng),和改變材料的狀態(tài)。所以晶體不僅有一個(gè)固定的熔點(diǎn)，而且需要吸收一定的熱量才能熔化。由于晶體空間的晶格結(jié)構(gòu)隨物質(zhì)的不同而不同，所以不同物質(zhì)熔化時(shí)吸收的熱量雖然質(zhì)量相同，但并不相同。

　　These heat will be used to increase molecular gravity and potential energy. That is to say, the energy required by the absorbed heat material will destroy the lattice structure, change the thermal motion of liquid molecules in the thermal motion of the qualitative solid molecules, and change the state of materials. So the crystal not only has a fixed melting point, but also needs to absorb a certain amount of heat to melt. Because the lattice structure of crystal space varies with the material, the heat absorbed by different substances during melting is not the same, although the mass is the same.
　　熔解熱被用來(lái)表示晶體物質(zhì)的這種性質(zhì)。它表示固體物質(zhì)在其熔點(diǎn)完全融化為相同溫度的液體所需要的單位質(zhì)量的熱量;當(dāng)物質(zhì)凝固時(shí)，在冰點(diǎn)，它也等于單位質(zhì)量的相同液體物質(zhì)轉(zhuǎn)化成晶體所釋放的熱量。如果是熔化熱，或者m是物質(zhì)的質(zhì)量，或者Q是熔化所需的熱量，那么的單位是焦耳每克或者焦耳每千克。高熔點(diǎn)物體的熔化熱難以測(cè)量，而低熔點(diǎn)物體的熔化熱可以用量熱計(jì)測(cè)量。
　　Melting heat is used to represent this property of crystalline materials. It denotes the heat per unit mass required for a solid to melt completely into a liquid at its melting point at the same temperature; when a solid solidifies, at freezing point, it equals the heat released by the transformation of the same liquid material per unit mass into crystals. If it's the heat of fusion, or m is the mass of the material, or q is the heat required to melt, then the unit is joule per gram or joule per kilogram. The melting heat of high melting point objects is difficult to measure, while that of low melting point objects can be measured by calorimeter.
