自制了演示气体做功与内能变化关系的实验装置，该实验装置利用热敏电阻探测密闭贮气筒内的气体温度，并用数字温度表直观地将温度显示出来，从而可以了解在贮气筒内气体做功时温度的变化，进而可以反映出气体内能的变化。

A device of demonstrating the changes in internal energy of gas as it expands was made . The device used a digital thermometer with thermistor to measure and display the temperature of the gas sealed in a cylinder .The temperature was showed accurately as the volume of the gas changed , and the changes in its internal energy were concluded .
