Again, the relative humidity will depend on how tall a glass might be (capacity) and how full that glass might be. If the glass is three-quarters filled, the relative humidity is 75 percent. Just to be an optimist, if the glass is half-filled, the relative humidity is 50 percent. Relative humidity becomes the ratio between the actual amount of water vapor present to the capacity that the air has at a particular moment. When it is filled to overflowing, the condition is called condensation. The point at which the atmosphere is totally filled is called saturation. So the whole process is a function of temperature.ĭew point is the temperature at which the vapor in the atmosphere becomes liquid. Eventually, you can even walk-or at least skate-on that water. If the temperature lowers even more, the molecules become closer. The water can take the form of a visible plume of steam, like a cloud, or just raindrops that form pools of water on the ground. If the heat is reduced, the temperature lowers, and the molecules no longer move around as much. The vapor itself comes from the water that is evaporated from the earth's surface, including oceans and lakes. The water molecules are far enough apart that the vapor is invisible. Like popcorn, water vapor molecules are bouncing around, thanks to heat in the atmosphere. But then, as heat is added and the temperature increases, the kernels start popping, and the popped corn moves around.

When the heat is first turned on, the kernels are just sitting there, solidly, on the bottom of the popper.
