Key Differences
Evaporation and condensation are fundamental processes in the water cycle. Evaporation occurs when water molecules from a liquid surface gain enough energy to transform into vapor, generally aided by heat. On the other hand, condensation happens when water vapor in the air cools and returns to a liquid state, forming droplets.
While evaporation is an endothermic process, which means it absorbs heat from its surroundings, condensation is exothermic, releasing heat. Evaporation, therefore, typically results in a cooling effect, while condensation tends to warm its surroundings.
Factors affecting evaporation include temperature, surface area, and humidity. The higher the temperature and surface area, the faster evaporation typically occurs, while high humidity slows it down. In contrast, condensation is influenced primarily by the temperature and humidity of the air; when air is saturated with moisture and cools, condensation is likely to occur.
The occurrence of evaporation is common in daily activities like drying clothes, sweating, or the steaming of a hot shower. Condensation, on the other hand, is seen when you observe water droplets forming on a cold glass of water or on windows during a cold day.
Both evaporation and condensation are essential in weather systems. Evaporation from oceans and lakes feeds moisture into the air, which can form clouds through condensation. When these clouds cool sufficiently, condensation can lead to precipitation.

Evaporation
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance.
Condensation
Condensation is the change of the physical state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle.

Common Curiosities
Is evaporation only restricted to water?
No, evaporation can occur with any liquid, but it's most commonly associated with water.
Does condensation only occur in cold conditions?
While it's common in cooler conditions, condensation can occur whenever air is saturated with moisture and cools.
Is boiling water an example of evaporation?
Yes, boiling is a form of rapid evaporation.
What leads to condensation on windows?
Condensation on windows results from moist air coming in contact with the cold surface of the window.
Why does evaporation cool the surroundings?
Evaporation is endothermic, absorbing heat from the surroundings.
Do both evaporation and condensation play roles in the water cycle?
Yes, both processes are fundamental in the water cycle.
Can condensation occur inside buildings?
Yes, especially when moist indoor air contacts cooler surfaces like walls or windows.
What causes evaporation?
Evaporation is caused by the increase in temperature and energy allowing liquid molecules to become vapor.
Why does my drink get cold when I add ice?
The drink gets cold due to the heat absorbed during the evaporation of the melting ice.
Why does the bathroom mirror fog up during a shower?
The hot water increases humidity, and when this moist air contacts the cooler mirror, condensation occurs.

Reducing humidity and increasing ventilation can help minimize condensation.
How does humidity affect evaporation?
High humidity slows down evaporation since the air is already saturated with moisture.
