中文百科

潜热

潜热,在热化学中,是物质在物态变化(相变)过程中,在温度没有变化的情况下,吸收或释放的能量。英文 latent (heat) 这个术语最初是由约瑟夫·布雷克发明,约于1750年从拉丁文的「latere」衍生而来,意即「隐藏」。潜热这个字一般已较少使用,取而代之的是现代观念的相变焓。

潜热可分为熔化热及汽化热,视乎当时热能的物态流动方向:

当相变是由固态转为液态再转为气态,能量改变是吸热性(endothermic)的;当相变是另一个方向的时候,能量改变是放热性(exothermic)的。由于在将水转水蒸气需要能量,水蒸气就是释放能量的物体。若水蒸气经由凝结或沉积转为液态或固态,保存了的能量会以能感受的热能释放。因此,当物体由固态转为液态,该物体将吸收潜热。相反,由液态转为固态,物体将释放潜热。

Latent heat 潜热

Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process that is specified in some way. An example is latent heat of fusion for a phase change, melting, at a specified temperature and pressure. The term was introduced around 1762 by Scottish chemist Joseph Black. It is derived from the Latin latere (to lie hidden). Black used the term in the context of calorimetry where a heat transfer caused a volume change while the thermodynamic system's temperature was constant.
