摘要
对电热法液体汽化热实验进行了研究,设计了新的实验装置.将盛液体的容器置于保温杯中,保温杯放置在电子天平上,液体由电加热器加热,液体蒸气由出气口排出,排出的液体蒸气的质量可由电子天平实时测量.装置改进后,测量更简单方便,结果更准确.
The experiment of liquid vaporization heat using electric heating method is studied and a new device is designed. The container is set in the insulation cup, and the insulation cup is put on the electronic balance. The liquid is heated by electric heater, liquid vapor is exhausted from the outlet, and the mass of exhausted liquid vapor is measured in real-time. The measurement method of improved device is better and the measurement result is accurate.
