Water vapor is an invisible gas, but the clouds of condensed droplets refract and scatter the sunlight and are thus visible. thumb|Droplets of water vapor in a pan. thumb|right|280px|Demonstration of evaporative cooling. When the sensor is dipped in ethanol and then taken out to evaporate, the instrument shows progressively lower temperature as the ethanol evaporates. thumb|Rain evaporating after falling on hot pavement
AI overview
Evaporation is the process where liquid water transforms into an invisible gas called water vapor. It matters because it's a key part of how water moves through the environment and can cool things down as it occurs.

蒸發是由於液體分子互相碰撞以及從環境中得到熱能補充（假設溫度不變，液體與環境處於熱平衡狀態），有些少數具有足夠動能且位於液體表面的分子，能擺脫分子間作用力而變成氣態從液體中逃逸出去的現象。蒸發僅限於液体表面汽化的过程，與另一汽化過程「沸腾」不同的是，蒸發只會發生於液體的表面，而且可在任何溫度發生。 在自然界中，蒸發是水循環的重要途径，太陽的能量使海洋、湖泊、泥土中的水分蒸發，形成雲。在水文學中，蒸發和蒸騰（植物葉片氣孔中水分的蒸發）合稱蒸散。在工业生产中，有的液体在沸点或低于沸点时会氧化或分解，需要进行（）。 在蒸发時，液体表面會有數個平均自由程的蒸氣薄膜，稱為克努森層。
