compare the melting point and freezing point of a substance.
试比较一种物质的熔点和冰点。
now. if you want to look at freezing point depression, it「s really easy.
如果你想看凝固点降低,这很简单。
frozen type air dryer by lowering the temperature of compressed air to close to the freezing point of water, that extra water vapor condense into liquid water, thus and flow separation.

any questions about those freezing point depression and boiling point elevation. yes.
有问题吗?关于凝固点降低,和沸点上升。
it lowers the melting and freezing point of water.
是因为食盐将水的熔点和冰点降低了。
because ice is less dense than water, andwater is less dense at its freezing point than when it is slightlywarmer, it freezes from the top down rather than the bottom up.
由于冰比水的密度低,冰点的水比温水的密度高,所以它会自上而下冻结,而非自下而上。
why does he choose 7-1/2 as the freezing point of water?
5,为什么他选择了7。 5作为2,水的冰点呢?
and we also drew a phase diagram to show how this vapor pressure lowering was going to imply freezing point depression and boiling point depression.
我们来画相图,蒸汽压下降,意味着凝固点降低,和沸点降低。
the moisture flow is a one-way process from smaller pores to larger pores because the water in larger pores has higher freezing point and freeze earlier than that in smaller pores.
这种迁移是从小孔向大孔的单向流动,原因在于大孔具有较高的冰点,在冻融循环降温阶段先于小孔中的水冻结,而在升温阶段迟于小孔融解。
evening temperatures drop to below freezing point in yushu, and there was a little snow and sleet on monday afternoon.
玉树的夜间温度降到零下,周一下午还下起了小雪转雨夹雪。
the separation of them is studied all the while. traditional methods include freezing point and gas chromatography, but the effect of separation is not so good.

secondly, various types of antifreeze due to the proportion of preparation, different ingredients, the freezing point is not the same, then should be based on local temperature conditions to choose.
其次,各类防冻液由于配制时的比例、成分不同,其冰点也不相同,这时应依据当地的气温条件来选用。
this is also since 1991, the first time china」s stock market unilateral stamp duty on securities transactions, which for almost freezing point in the stock market is timely help.
