铝板生产厂家给您讲一讲铝的比热容和熔化热!

来源:

  铝的比热容为0.88×103 J/(kg·℃),熔点为660.37。铝的熔化热为3.98×105J/kg,铝的蒸发热为1.05×107J/kg。熔化热:单位质量晶体物质在熔点从固相到液相吸取的相变潜热。晶体的熔化是粒子由规则排列变为不规则排列的过程。
  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.
  这些热量将用于对分子引力,分子势能增加,也就是说,吸取的热量材料所需要的能量破坏晶格结构,使分子运动状态改变质变的固体分子热运动的液体分子热运动,和改变材料的状态。所以晶体不仅有一个固定的熔点,而且需要吸取一定的热量才能熔化。由于晶体空间的晶格结构随物质的不同而不同,所以不同物质熔化时吸取的热量虽然质量相同,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.
  熔解热被用来表示晶体物质的这种性质。它表示固体物质在其熔点完全融化为相同温度的液体所需要的单位质量的热量;当物质凝固时,在冰点,它也等于单位质量的相同液体物质转化成晶体所释放的热量。如果是熔化热,或者m是物质的质量,或者Q是熔化所需的热量,那么的单位是焦耳每克或者焦耳每千克。高熔点物体的熔化热难以测量,而低熔点物体的熔化热可以用量热计测量。
  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.
