测定水的汽化热L是普通物理热学的一个基本实验,过去教学中常用的装置(如图1)有以下缺点:1。燕汽锅2。滋水筒3。放水管4.陇热板5。t热器6。搅拌器7.沮度什8.蒸汽导管一、所用的蒸汽质量难以测准,这是因为实验时不可避免地有水(在通汽管壁上凝结的)随蒸汽进入量热器中 Determination of heat of vaporization of water L is a basic physical thermal experiment, the past teaching devices commonly used (Figure 1) has the following disadvantages: Yan steam pot 2. Nourish tube 3. Water pipe 4. Long hot plate 5. T heater 6. Stirrer 7. Disturbance 8. Steam Duct I. The quality of the steam used is difficult to calibrate because of inevitable water (coagulated on the walls of the vent) entering the calorifier with steam during the experiment
