Difference Between Evaporation And Condensation

Evaporation and Condensation are the words we have often heard while studying liquids in chemistry. These words sound the same but they are different when it comes to the nature of the processes. Besides, water is usually used as an example to understand the concept of Evaporation and Condensation.

What is Evaporation?

Evaporation is the scientific phenomenon by which liquid can be converted to vapor or its gaseous form. The word “vapor” used in evaporation itself helps to remember the meaning.

Evaporation occurs when the temperature increases, which increases their kinetic energy or we can say more movement of molecules by which they overcome the intermolecular forces of attraction and form liquid. It occurs in liquids only because the intermolecular forces between solids are very high so the molecules cannot get free to form gas.

What is Condensation?

Condensation is a scientific phenomenon by which vapor can be converted to liquid the word ‘condense’ means to change from vapor to liquid. It occurs when the temperature of gas or liquid decreases and the molecules lose kinetic energy and have very little movement which causes them to bind together and form a liquid.

Evaporation v/s Condensation

Evaporation	Condensation
It is a process by which liquid changes into gas or vapor.	it is a process by which gas or vapor changes into liquid.
Evaporation is an endothermic process, which means that it requires energy in the form of heat to occur.	Condensation is an exothermic process, exothermic are processes that release energy in the form of heat.
Evaporation begins from the surface of the liquid when temperature increases.	It happens in a gas or vapor in which its temperature decreases.
During evaporation, the molecules in a liquid gain energy by heat and move more rapidly, causing them to escape the surface of the liquid and enter the surrounding air as a gas.	During condensation, the molecules in a gas lose energy and move more slowly, causing them to come together and form a liquid.
Force of attraction between the particles increases in this process.	Force of attraction between the particles decreases in this process.
Examples of evaporation include drying clothes, boiling water, sweating, etc.	Examples of condensation include fog, dew, and cloud formation, etc.

Conclusion

Hence we can say that evaporation and condensation are two opposite processes that are necessary for the water cycle and many other physical and biological systems. These two processes are interconnected as when evaporation occurs due to the addition of heat energy leads to an increase in the water vapor present in the air, and can also undergo condensation in the right conditions.

For example- water evaporates by heat energy then its vapor goes up in the air and cools down to form tiny water droplets, fog, or clouds. Understanding these processes is necessary for a wide range of applications from understanding weather to purifying to designing new materials.

Difference Between Evaporation And Condensation – FAQs

What is the difference between vaporization and condensation ?

In the Vaporization process liquid is vaporized into a gas, where as in the Condensation vapours are converted back to the liquid.

What are two differences between evaporation and boiling ?

Evaporation usually occurs on the heated liquid’s surface whereas Boiling usually occurs on the entire mass of the liquid that gets heated up inside the surface. Bubbling effect is not visible in evaporation whereas Bubbling effect is visible during the process of boiling.

What are some ways to prevent condensation?

Some ways to prevent condensation include improving ventilation, reducing moisture levels, and using dehumidifiers.

How does Evaporation affect the level of water?

The level of water from sea oceans lakes will decrease as it is exposed to sunlight during evaporation.

How long does it take for Evaporation?

The speed of molecules of water increases, its kinetic energy increases until its enough that it can escape in form of gas. As it moves up in the air above temperature is quite low so it cools down and stays in the air for 9-10 days.

How are the Process of Perspiration and Evaporation similar?

Perspiration is a kind of evaporation that occurs in our body. The water in our body evaporates, by taking energy from our body which results in lowering our body temperature.
