电热法测定冰的熔化热实验仪的研制

Experimental instrument of measuring the melting heat of ice by electrothemal method

为了解决混合法测量冰的熔化热实验中热量损失的问题,设计了电热法测定冰的熔化热实验仪.真空保温杯和冰水混合物双重隔离实验对象,降低了冰与环境的热交换,通过移液管测量冰熔化成水的体积变化,进而测定冰的熔化热.

In order to solve the problem of heat loss in measuring the melting heat of ice by using blending method, an experimental instrument of measuring ice melting heat using electrothermal method is designed. The experimental object is separated by vacuum bottle and mixture of ice and water, for decreasing the heat exchange of ice from environment. The volume variety of ice during melt process is measured by the move-liquid tube, and the melting heat of ice is also measured.
