关于基本的化学热力学:解决存储可再生能源的挑战Virtual Lab Simulation
这是全长的“基本化学热力学”模拟。对于较短的，更具针对性的版本，请参见下面的相关模拟。华体会赞助ac米兰
能源是我们这个时代的重要主题之一，但是能量实际上是什么？在此模拟中，您将学习焓，熵和吉布斯自由能的基本热力学概念。您还将通过使用炸弹量热法确定化合物的内部能量，甚至可以在量热计中行驶以在作用中看到它！
The challenge of storing energy
What is the best way to store energy? There is no simple answer, but in this simulation, you will be encouraged to give it some thought while learning about the very nature of energy and how it connects to chemical reactions. You will assess whether the gasoline component辛烷is a suitable chemical for energy storage by using a bomb calorimeter.
热力学的基本概念
在此模拟中引入了热力学的第一和第二定律以及焓，熵和吉布斯自由能的核心概念。您可以在虚拟能表面上使用反应物和产品的能量水平来了解吸热和放热反应。反应自发性的概念与Gibbs自由能的概念有关，并且在互动游戏中探索了其温度依赖性。您将可以访问最先进的炸弹量热计，并可以在内部旅行以查看它的作用，以便能够真正了解其工作原理。从这里开始，化学键能的概念与量热计输出的焓的热力学计算有关。
Combine theory and practice
Throughout the simulation you will combine the fundamental teachings of thermodynamics with the experimental results from the calorimeter.
Will you be able to suggest a solution for the energy storage challenge?
