The 32 Most Important Examples of Evaporation

Some of the most important examples of evaporation are simple water drying, sweat evaporation, salt extraction, ocean ocean evaporation, natural drying of the body after bathing, among others.

Evaporation is the process by which water changes its liquid state from gas or vapor. Water boils at 212 degrees Fahrenheit or 100 degrees Celsius, but starts to evaporate at 32 degrees Fahrenheit or 0 degrees Celsius. As the temperature increases, the rate of evaporation also increases.

Evaporation is one of the phases of the water cycle.

The amount of evaporation depends on the temperature and the amount of water. For example, there is not much evaporation in the Sahara desert, but why? Although it can be extremely hot, there is only sand in the Sahara; There is not much water to evaporate.

If a liquid molecule gains enough energy in the form of ambient heat, it becomes vapor.

Evaporation takes place at the surface of a liquid, not through the body or total volume. When evaporation takes place, the pressure of the vapor is less than the pressure of the surrounding atmosphere.

Evaporation is a process by which atoms or molecules that are in a liquid state (or a solid state, such as ice) obtain enough energy to enter gaseous form.

List with evaporation examples

Evaporation is a chemical phenomenon with a high incidence in everyday life and also in industrial and research processes. Every day, we encounter this process without looking at it.

1- Drying clothes in the sun

Many people put freshly laundered clothes in the sun to dry. In fact, water is removed from the fabric by evaporation, a product of the heat in the environment.

2- Drying water on the streets

When it rains, the city’s streets often form pools of water that are easily observable, but with a very short duration. This is because evaporation takes place and evaporates water from these puddles, turning it into steam.

3- Evaporation of seas and oceans

While this is a little harder to observe, the seas and oceans are constantly evaporating, which causes rain. Water rises into the clouds and makes them charge, causing precipitation.

In coastal cities, humidity is always constant, because the water from the sea mixes with the environment, giving the feeling of humidity and a heavy environment.

4- Tea cooling

The tea is cooled, giving the product the steam that emanates from the cup. This makes the heat dissipate and allows us to drink tea. The hot molecules on the surface are evaporated, taking the heat with them.

5- Evaporation of perspiration from our body

The sweat from our body evaporates, taking away the heat. Sweat manages to evaporate due to its liquid characteristic.

6- Drying the wet floor

As in puddles, when a little liquid is spilled on the floor or wiped off, the heat causes it to evaporate, leaving it completely dry.

7- Evaporation of nail paint remover

When acetone is applied to the nails to remove the enamel, it is evaporated by the caloric action.

8- Dry ice

Dry ice, when removed from its cooling, evaporates due to the pressure exerted by heat to break the surface tension of the ice.

9- Ice cube

When removing an ice cube, it starts to melt and takes the form of a liquid (water) that will be evaporated by the action of heat.

10- Internal water in pans

Normally, when boiling water and covering it, the object used as a covering is impregnated with a few drops of water from the steam that does not escape from the pan.

11- Evaporated water from the pan

When cooking meat, for example, some cooks add water to the pot to soften the product. Water evaporates as a result of the heat exerted by the flame in a very short time.

12- Exit

Salt is created as a result of the evaporation of seawater through industrial or natural processes, resulting in salt crystals.

13- Natural drying of the body

After showering or getting out of a pool or beach, we don’t need towels, because the same heat causes our bodies to dry at a slower but safer rate.

14- Distillation

Distillation is a process in which two mixtures are separated by boiling. For this, evaporation allows the separation of substances.

15- Cooling Towers

This is one of the most important applications of evaporation. The most iconic cooling towers are those seen in photographs of nuclear power plants.

Here water is used to cause steam which ignites the turbines to generate electricity. It releases energy through the evaporative process before returning to its cycle.

16- Evaporation to dry or concentrate samples

It is a common and preparatory step for many laboratory analyses, such as chromatography. These systems used for this purpose include rotary evaporators and centrifugal evaporators.

17- The Matka

It is a porous vessel from India that acts as a container for storing and cooling water and other liquids.

18- The bottle

A traditional Spanish instrument that fulfills the same function as Matka. It works to cool the water contained in this vessel.

19- Evaporative coolers

They can significantly cool a building simply by blowing dry air through a filter saturated with water.

20- Product Concentration

It allows the concentration of some product to obtain, for example, molasses in the sugar industry.

21- Crystallization

Evaporation is also used for crystallization.

22- Food Processing

It is used to process milk, coffee, juices, vegetables, pastes and concentrates.

23- Vaporization combustion

Gasoline drops evaporate as soon as they receive heat, mixing with hot gases in the combustion chamber. Caloric energy can also be received by radiation emanating from any refractory chamber in the combustion chamber.

24- The steam from a pressure cooker

These pressure cookers produce great heat inside, with a small seal where the steam exits.

25- Pass

Ironing is also an example of vaporization. Some irons require water, which is then evaporated and allows the fabric to be ironed.

26- Cloud formation

Clouds are formed by water, mixed with other chemical components such as oxygen and helium.

27- Saunas

Saunas Hot springs are steamed waters, where heat relaxes the muscles of the body.

28- Evaporation of small lakes and ponds

29- Kitchen

Evaporation produced by boiling water to make coffee or tea. Steam is also an example of evaporation.

30- Acceleration of production processes

Evaporation is a natural phenomenon with a high incidence in the daily lives of humanity.

It is also used industrially to speed up production processes, as well as in the pharmaceutical and chemical industry for distilling and obtaining mixed substances.

31- Obtaining energy

Evaporation is also used as an energy-gathering mechanism; look at nuclear or hydroelectric plants, where evaporation plays a key role in energy processes. As noted above, steam causes turbines to ignite and release energy.

32- Air conditioning

Air conditioners also evaporate water through steam, artificially generating the characteristic cold of these devices.

Not to be confused with boiling, as this requires essential physical condition and a temperature above 100 degrees Celsius. However, evaporation can occur at temperatures from 0 to 100 degrees.

Note that in cities with higher humidity, there is water in the environment in the form of steam, due to its proximity to the coast.
