学生对“外体积守恒任务”的回答与“温度计受热液体的质量不变任务”的回答相关异常显著。
There is a very positive correlation between the task of conservation of external volume and the task of the mass of liquid keeping in the same in the thermometer, as it is heated.
在建立多孔介质各相质量守恒方程时，液体蒸发量相对于蒸汽相而言为质量源，对液相本身而言为质量汇。
Evaporation quantum of liquid is expressed as mass source for vapor in vapor mass conservation equation, while it is dealt with mass sink for itself.
根据能量守恒定律，液体变为固体时放-出的热量必定等于该固体变为液体时所需的热量。
According to the Law of Conservation of Energy heat equivalent to that which is required to change a solid into liquid must be given out when the reverse change takes place.
