英语翻译When water is heated,it turns into vapor,when vapor is cooled,it turns into water.The air can hold certain amount of vapor at certain temperature.As the temperature goes up,the air can hold more.So heated water turns into vapor.vapor travels with air.When the air becomes cooler,it cannot hold that much vapor.Then vapor becomes water.When water falls from sky,it's called "rain".

When water is heated,it turns into vapor,when vapor is cooled,it turns into water.The air can hold certain amount of vapor at certain temperature.As the temperature goes up,the air can hold more.So heated water turns into vapor.vapor travels with air.When the air becomes cooler,it cannot hold that much vapor.Then vapor becomes water.When water falls from sky,it's called "rain".
当水被加热,它就变成蒸汽,当蒸汽冷却后,它成为水。空气在一定的温度条件下能够承受一定数量的水蒸气。随着温度的上升,空气能承受更多。因此加热水后成为蒸汽,蒸汽随空气一起流动。当空气受冷时,它不再能承受那么多的水蒸汽。然后蒸汽变成水。当水从天空落下来,就是人们所谓的“雨水”。
当水被加热时,就会变成蒸汽,蒸汽冷却时,它会变成水。空气在某一温度下可以容纳一定量的蒸气。随着温度的升高,空气可以容纳更多。因此被加热的水变成蒸汽。蒸气游离在空气中。当空气冷却,它不能容纳太多蒸气。然后蒸气变成水。当水从天空坠落,它被称为“雨”。
当水被加热后,它会转化成水蒸气,当水蒸气受冷,它会转化为水.空气在一定的温度下能承受一定的水蒸气.当气温上升的时候,空气可以承受更多.因此加热的水转化为水蒸气,水蒸汽和空气一起移动.当空气变冷的时候,它就不能承受那么多的水蒸汽了.然后水蒸汽成为水,当水从天际降落,那就是“雨”
当水被加热,它变成蒸汽,蒸汽冷却时,它就变成了水。空气可以持有一定数量的蒸汽在特定的温度。随着温度上升,空气可以持有更多。所以加热水变成蒸气。蒸汽与空气传播。当空气变冷,它不能保存这么多蒸汽。然后蒸汽变成水。当水从天空坠落,它叫做“雨”。
