英语翻译
Put an ice cube(冰块) from your fridge into a glass of water.You have a piece of ice with the help of the string.But you must not touch the ice with your fingers.
You may ask your friends to try to do that when you are having dinner together.There is a salt-cellar(盐瓶) on the table.You must use salt when you carry out this experiment.
Frist,you put the string across the piece of ice,and then put some salt on the ice.Salt makes ice melt.The ice round the string will behin to melt.But when it melts,it will lose heat.The
cold ice cube will make the melted water freeze again.
After a minute or two you may raise the piece of string and with it you will raise your piece of ice!
this experiment can be very useful to you.For example ,if there is ice near the door of your house,you may use much salt to melt all the ice.If you don't put enough salt,the water will freeze again.
英语翻译Put an ice cube(冰块) from your fridge into a glass of wat
往一个杯子离投入一块从冰箱里拿出的冰块.你可以用一根细线拿着一块冰,但是你千万不能直接用你的手指去碰触这块冰.
在你准备午饭的同时,你可以请你的朋友来尝试这么做.桌子上有一只盐瓶.进行这项实验你需要用到盐.
首先,将细线绕过这块冰,然后向冰面撒上一些盐.盐使得冰块融化.细线周围的冰将会开始融化.但是当它融化时,它也会放热.寒冷的冰块将会令已融化的水重新冻结起来.
一到两分钟后,你提起这根细线,你将发现你提起了你的那一整块冰.
这个实验将会给你带来不少用处.比如说,如果你家门边上结了冰,你就可以使用大量的盐来溶解所有的冰.如果你没有撒上足够多的盐,(被融化的)水将会再度结冰.
