Description
In the case of misty lakes in the morning, all these processes are happening, just like in the example of the boiling pot, except the temperatures are far lower. Throughout the summer, the lake has absorbed and retained a large amount of heat energy in the top layer of the lake. At night -- especially on cloudless nights -- the heat energy in the air rises away from the surface and escapes this local system, thus bringing down the temperature. There is evaporation taking place in the lake, both day and night, thanks to the higher temperatures of the surface of the lake. However, unlike during the heat of the day, at night, since there is a lower temperature, there is less capacity for the air to hold on to gaseous water, and we can measure this as an increase in humidity. As the humidity rises to 100%, the air has a diminishing capacity to hold on to all the water that is evaporating -- due to the heat of the water in the lake -- and so the water almost immediately condenses into mist as it rises from the lake. In fact, if you heat a pot to the same temperature of the lake water, you would see steam flowing up from your pot, even though the water temperature is nowhere near boiling.
Once the sun's rays strike the surface of the water, the humidity is "burned away", in that the local temperature increases enough so that the humidity drops below 100%, thus allowing the air to once again absorb the evaporating water.
