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 »

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 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 »

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 »

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 »

Water boils when the thermal energy in the water, which is a type of kinetic energy which causes the water molecules to move around, exceeds the strength of the hydrogen bonds between the molecules, causing them to separ... More »

When a material or substance cools and goes from a gas state to a liquid state, this process is known as condensation. More »
