evaporation of water
水的表面积 surface of water

? 在两个不同大小的杯子中倒入50毫升的水,在杯子外做标 记,把它们放在相同的地方。 ? Pour 50ml of water into two different sizes of glass, take marks outsideand the cup and put them in the same place.

? 一天后,表面积大的先蒸发完,表面积小的蒸发了一半。 ? One day later, the water with larege surface has evaporated, but the water with small surface hasn't.

? 所以,水的表面积影响水蒸发的快慢:表面积越大,水蒸 发的越快。 ? So, surface of water affect the evaporate of the water: The larger the surface of water is, the faster the water evaporates.
