How are vaporization and condensation related?
4 Answers | add yours
Condensation and vaporization are, in essence, opposite phenomena.
When a liquid (say water) gets hot enough, it vaporizes and becomes a gas.
By contrast, condensation is the process whereby a gas changes back into a liquid. This happens when a gas comes in contact with a surface that is cool enough to make the gas return to a liquid state.
A good example of condensation is when dew forms on grass in the morning. In this case, there is water vapor in the air that condenses on contact with the ground, which is cool enough to cause the condensation.

Condensation and vaporization are two processes that are reverse of each other. Condensation is the process of conversion of a gas into liquid and vaporization is the process of converting liquids into gas or vapours. Some solid substances, for example camphor, get vaporized to gaseous state without passing through the liquid state. This process is called sublimation.
Vaporization, also called evaporation when due to kinetic energy within molecules of substances some molecules escape from the surface of solid or liquids and get converted to gaseous form. Substances that get vaporized easily or at faster rate are called volatile substances, and ones that do not are called non-volatile. The volatility of substances increases with temperature as with increase in temperature the kinetic energy of molecules increases.
The process of evaporation and condensation occurs in nature for water all the time resulting in earth's water cycle. The water from earth's water bodies gets evaporated to form clouds, and these clouds then condense into rain.
The process of evaporation and condensation is also used by humans in processes such as fractional distillation of mixtures of different liquids and for concentration of solids dissolved in liquids.

I love a hot, steamy shower in the dead of winter. The steamy water vapor floats through the air and comes to rest on the mirror. The cold mirror converts the vapor from a gas state to a liquid state. The cold air makes the water molecules slow down and form water droplets. This is called condensation.
How do you see yourself in the mirror? You can open the door and let some warm air in. The warm air causes the water to change from a liquid to a gas. The heat makes the water molecules speed up and escape from the surface. This is called evaporation.
They are related in that temperature effects both the liquid and gas states of water molecules in condensation and evaporation.

Vaporization, or evaporation, is the process in which a liquid is heated until it becomes a gas. A simple example would be a puddle of water being heated by the sun, would seem to disappear as the water molecules evaporate. As these molecules collect in the sky they condense into larger molecules, thus in turn becoming water again. Therefore vaporization and condensation are opposite processes. Vaporization being the breaking down of a liquid into a gas, and condensation being liquid accumulating.
