how do puddles evaporate/dry up on cold days?
In: Chemistry
The molecules in liquid water are held together slightly so that they are pretty much free move around as long as they stay next to each other. When the molecules have enough kinetic energy to escape the force holding them together, the molecules are considered water vapor.
Temperature describes the average amount of heat energy. At any given temperature, some water molecules can have more energy and some less. Even in very cold water, some of the most energetic molecules can have enough energy to escape. The hotter the water is, the more likely it is for molecules to escape.
