Dew is a fantastic example of atmospheric physics at work. As the sun goes down and less sun rays hit the ground, the grass cools down quickly as it loses heat to the open sky. When the grass gets below the air temperature, the surface temperature will drop to equal the dew point of the atmosphere. This means the air will reach 100% humidity ($100\%$) at the edge of the grass. Condens... https://bettbhai9.cc/
