About Matter and Phase Changes:蒸馏乙醇虚拟实验室模拟
准备遇到所有三个物质的州。在此模拟中，您将操纵物质状态并检查相变。你能看到几乎你与事项互动的一切吗？
Explore the intermolecular forces in matter
In the Matter and Phase Changes simulation, you will meet Jo who has a limited fuel supply and therefore wants to produce bioethanol. In order to help her, you must first master the definition of matter and the process of phase changes. You will dive into the water and examine the dynamics of intermolecular forces of water molecules during the phase changes. With the help of 3D animations, you will learn about the molecular configuration in three states of matter: Solid, liquid, and gas.
Generate heating curves
一旦您掌握了基础知识，您就可以了解阶段的其他方面，更改：特定的热量，潜热和压力。您将利用温度探针和加热板来产生加热曲线，然后比较水，乙醇和金属的加热曲线。通过这样做，您将能够解码加热曲线的每一行的含义。
Perform distillation
在模拟结束时，您将新获得的知识放在测试中！您将使用蒸馏技术来实现具有更高纯度的乙醇。
Will you be able to produce high purity ethanol for Jo?
