enthalpies

enthalpy的音标为：[ɪnˈθæləpɪ]

基本翻译为“焓”或“热焓”。

速记技巧：可以记为“能量焓”或“热能量”。

请注意，以上内容仅供参考，具体含义和用法可以查阅英语词典。

Enthalpy这个词的英文词源可以追溯到拉丁语“enthalpiae”，意为“热能”。它的变化形式包括“enthalpy”和“enthalpyic”。相关单词包括“enthalpization”、“enthalpy-entropy diagram”、“enthalpy-temperature diagram”、“enthalpy-volume diagram”、“enthalpy change”、“enthalpy of formation”、“enthalpy of reaction”、“enthalpy of combustion”和“enthalpy of vaporization”。这些单词都与热力学中的热容和能量变化有关，描述了化学反应和物质状态变化过程中的能量转换。这些单词在描述化学和物理过程时非常重要，有助于科学家和工程师理解物质和能量的相互作用。

英文小作文：

Enthalpy is an important concept in chemistry and physics, and it refers to the energy required to change a substance from one state to another. For example, the enthalpy of fusion refers to the energy required to melt a substance, while the enthalpy of vaporization refers to the energy required to turn a solid or liquid into a gas. These two processes are very common in daily life, and understanding their enthalpy values can help us better understand how substances behave under different conditions.

Another important application of enthalpy is in combustion reactions, where the heat released during the reaction can be used for various purposes, such as heating or power generation. Understanding the enthalpy of combustion can help us predict how much energy will be released during a combustion reaction and how efficiently it can be used.

In summary, enthalpy is a fundamental concept that plays an important role in understanding the behavior of substances under different conditions. Understanding enthalpy can help us better understand our world and develop more efficient and sustainable methods of using energy.
