热使水变成蒸气。

Heat turns water into vapor.

根据我的记忆，水往复地变化，从湖泊和海洋里的水变成水蒸气，然后当它以雨或雪——也就是降水的形式落下时又变成水。

From what I remember, water changes back and forth from water in lakes and oceans to vapor, and then back to water again when it falls as rain or snow, as precipitation.

对水源管理者来说，只有在水通过物理蒸发变成空气的一部分，或者被植物吸收并且转变为水蒸气形式(蒸腾作用)的时候，才被消耗了。

For a water manager, the only time water is consumed is when it evaporates into the air or is soaked up by plants and then turned into water vapor (transpiration).
