你需要什么?一只玻璃杯一些小冰块一些盐一支温度计开始动手喽当我们把小冰块放入手中时,会感觉很冷。用温度计测量一下小冰块的温度,大约接近零度。现在往玻璃杯中放入大量的冰块,并倒入—些水,一直灌到玻璃杯的边缘,然后将温度计放入玻璃杯,读—读度数。记下度数了吗?现在,我们再往杯中撒些盐试试看。 What do you need? A glass of ice and some salt A thermometer starts to work. When we put small ice cubes into our hands, it feels cold. Use a thermometer to measure the temperature of the ice cube, which is approximately zero degrees. Now put a lot of ice cubes into the glass and pour some water in until the edge of the glass, then put the thermometer into the glass, read-read the degree. Did you remember the degree? Now, let’s try some salt in the glass.
