  • The latent internal energy of a system is the internal energy a system requires to undergo a phase transition. Its value is specific to the substance or mix of substances in question. The value can also vary with temperature and pressure. Generally speaking the value is different for the type of phase change being accomplished. Examples can include Latent internal energy of vaporization (liquid to vapor), Latent internal energy of crystallization (liquid to solid) Latent internal energy of sublimation (solid to vapor). These values are usually expressed in units of energy per mole or per mass such as J/mol or BTU/lb. Often a negative sign will be used to represent energy being withdrawn from the system, while a positive value represents energy being added to the system. However, reference sources do vary so check the source to be sure. For every type of latent internal energy there is an opposite. For example, the latent internal energy of Freezing (liquid to solid) is equal to the negative of the Latent internal energy of melting (solid to liquid) (en)
  • 潛內能是指系統要產生相變時的內能變化,會隨系統的成份(純物質或混合物),溫度及壓力,以及要產生的相變而不同。例如汽化热、熔化熱、昇華熱等。潛內能一般會用單位質量或是單位莫耳下的能量來表示,例如J/mol或BTU/lb。正號表示能量加入系統中,負號表示從系統中移出能量。不過各參考資料也可能會有不同的定義。 每一種潛內能都有一潛內能與其數值相同,但符號相反,例如熔化(固態變為液態)的潛內能數值就和凝固(液態變為固態)的潛內能數值相同,但符號相反。 这是与熱力學相关的小作品。你可以通过编辑或修订扩充其内容。 (zh)
