热力学第一定律的确立,经过了漫长的时间和许许多多科学家坚持不懈的实验研究,是人类生产生活经验的完美总结,对热力学领域的发展具有很重要的作用,其也具有广阔的应用前景。本文从高中生的角度分析热力学第一定律,并对其应用做了相关探讨,对我们深入理解热力学第一定律起着重要的指导作用 The establishment of the first law of thermodynamics, after a long period of time and persistence of experimental research by many scientists, is the perfect summary of human production and life experiences and plays an important role in the development of thermodynamics. It also has broad application prospects . This paper analyzes the first law of thermodynamics from the perspective of high school students and makes a discussion on its application, which plays an important guiding role in our understanding of the first law of thermodynamics
