气体压力实验（分析压力、密度、温度及体积关系）

一系列的气体压力测试实验，用以展示气体压力、密度、温度及体积之间的关系。

Gas pressure experiment (pressure, density, temperature, volume)

 The objective of the pressure experiment was to learn and analyze the relationship among the pressure, density, temperature, volume, and understand the gas constant, the ideal gas law, to explore the properties of an ideal gas. And also, we learned to calculate work forma l-v the graph, and how to use the mathematical methods to solve the practical problems. The phenomenon of pressure experiment and the pressure analysis are very interesting and amazing.
