When water vapor cools, it condenses. It is a phase change where water changes from a gas to a liquid. Condensation is the opposite of evaporation. More »

Rain occurs through the process of coalescence, where a mass of water droplets gathers around cloud condensation nuclei to saturate the atmosphere and allow condensation and precipitation to take place. This process is d... More »

A typhoon is a tropical cyclone that occurs in the Northwest Pacific Ocean, explains the National Ocean Service. Typhoons, cyclones and hurricanes are all the same type of weather disturbance, but different names are use... More »

Condensation nuclei are tiny particles of solid or liquid in the atmosphere that trigger water vapor to begin condensing into water droplets and forming clouds. Any particles that are attractive to water molecules, namel... More »

The process of a gas changing to a liquid is called condensation, and for condensation to take place, the environment has to reach maximum vapor pressure, generally through a lowering of temperature in the case of the wa... More »

The air is primarily composed of five gases: nitrogen, oxygen, argon, carbon dioxide and water vapor. In addition to these five gases, there are also trace amounts of several gases, but these make up much less than one p... More »

When water freezes, the molecules slow down and assume a fixed position, although not quite in the way that one might think. Water is made of molecules with two hydrogen atoms and an oxygen atom, but those molecules don'... More »
