The 32 Most Important Examples of Evaporation

Some of the evaporation examples The most outstanding are the simple drying of water, the evaporation of sweat, the extraction of salt, the evaporation of the sea from the ocean, the natural drying of the body after a shower, among others.

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

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, in the Sahara there is only sand; there is not much water to be evaporated.

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

Evaporation occurs at the surface of a liquid, not through the entire body or volume. When evaporation occurs, the pressure of the vapor is lower 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) gain enough energy to become a gas.

List with examples of evaporation

Evaporation is a chemical phenomenon with a high incidence in daily life and also in industrial and research processes. Daily we come across this process without noticing it.

1- Drying clothes in the sun

Many people put freshly washed clothes out in the sun to dry. In fact, the water is removed from the fabric through evaporation, due to the heat in the environment.

2- Drying the water in the streets

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

3- Evaporation of seas and oceans

Although this is a little more difficult to observe, the seas and oceans are constantly evaporating, which causes rain. The water rises to the clouds and causes them to be charged, causing precipitation.

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

4- Cooling the tea

The tea cools, giving off the steam emanating from the cup as a product. This causes the heat to dissipate, and allows us to drink the tea. Hot molecules on the surface evaporate, taking the heat with them.

5- Evaporation of perspiration from our body

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

6- Drying the wet floor

As with puddles, when a liquid is spilled on the floor or cleaned, the heat causes this liquid to evaporate, leaving it completely dry.

7- Evaporation of nail paint remover

When acetone is applied to nails to remove polish, it is evaporated by heat action.

8- Dry ice

When dry ice is removed from its refrigeration, it evaporates due to the pressure exerted by heat to break the surface tension of the ice.

9- Ice cube

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

10- Internal water in kitchen pots

In general, when boiling water and covering it, the object used as a lid is impregnated with a few drops of water produced by the steam that could not escape from the pot.

11- Evaporated water from the pan

When cooking meat, for example, certain cooks add water to the pan to soften the product. The water evaporates by itself as a result of the heat exerted by the flame in a very short time.

12- Salt

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

13- Natural drying of the body

After taking a shower or leaving a pool or beach, we don’t need a towel because the same heat causes our body to dry out at a slower but safer speed.

14- Distillation

Distillation is a process in which two mixtures are separated through boiling. To achieve 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 plants.

Here the water is used to create steam that turns turbines to generate electricity. It releases energy through the evaporative process before it cycles back.

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 handicraft from India that acts as a container for the storage and cooling of water and other liquids.

18- The jug

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

19- Evaporative coolers

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

20- Concentration of products

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, pasta and concentrates.

23- Vaporization Combustion

Gasoline droplets vaporize as soon as they receive heat, mixing with hot gases in the combustion chamber. Heat energy can also be received by radiation emanating from any refractory chamber of the combustion chamber.

24- The steam of a pressure cooker

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

25- Ironing

Ironing is also an example of steaming. 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

The saunas. The thermal waters are vaporized waters where the heat relaxes the muscles of the body.

28- Evaporation of small lakes and lagoons

29- Kitchen

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

30- Acceleration of production processes

Evaporation is a natural phenomenon with a high incidence in the day to day of humanity.

It is also used industrially for the acceleration of production processes, as well as in the pharmaceutical and chemical industry for distillation and obtaining mixed substances.

31- Obtaining energy

Evaporation is also used as a mechanism to obtain energy, see nuclear plants or hydroelectric plants where evaporation plays a fundamental role in energy processes. As noted above, the steam causes the turbines to turn on releasing energy.

32- Air conditioners

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

It should not be confused with boiling, because for this an essential physical condition is needed and a temperature above 100 degrees Celsius. However, evaporation can occur at temperatures from 0 degrees to 100 degrees.

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