endothermic

endothermic的音标为[ɪnˈdɔːtərmɪk]，基本翻译为“吸热的；内热的”，速记技巧为：指物质吸收外来热量的过程，是化学反应的一种方式。

Endothermic这个词源自希腊语，意思是“吸收热”。它的变化形式包括名词的复数形式endotherms，形容词形式endo-thermic。相关单词包括：endothermicity（吸热性），endotherm（吸热物），exothermic（放热反应），endothermic reaction（吸热反应），endothermicity test（吸热性试验），endo-thermic gradient（内热梯度）。

这些单词在生物学、化学和物理学中都有广泛的应用。例如，在化学中，我们经常使用endothermicity来描述化学反应中吸收热量的倾向。在生物学中，我们使用endo-thermic gradient来描述细胞内温度和环境温度之间的差异。这些单词的使用可以帮助我们更好地理解和描述自然世界中的各种现象。

常用短语：

1. endothermic reaction 吸热反应

2. endothermic process 吸热过程

3. endothermicly 吸热地

4. undergo an endothermic reaction 发生吸热反应

5. heat endothermically 吸热

6. absorb heat endothermically 吸热吸热

The Difference between Endothermic and Exothermic Chemical Reactions

Chemical reactions can be classified into two types: exothermic and endothermic reactions. Exothermic reactions release heat, while endothermic reactions absorb heat. This difference in heat production or absorption determines the direction of heat flow in the chemical system.

Exothermic reactions occur spontaneously due to the release of energy, which leads to an increase in temperature and the expansion of gases. Conversely, endothermic reactions require external energy input to proceed, which leads to a decrease in temperature and contraction of gases. This difference in behavior can have profound implications in various chemical processes, such as combustion, hydrolysis, and chemical synthesis.

In addition to their effect on temperature, exothermic and endothermic reactions also have different effects on chemical products and products of reactions. Understanding these differences is crucial for effective chemical analysis and optimization of chemical processes. Furthermore, the application of exothermic and endothermic reactions extends beyond the laboratory setting, as they are integral parts of various industrial processes, including fuel combustion, manufacturing processes, and food processing.
