| Abstract: | 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. |
