Temporary changes in form are usually demonstrated through the processes of freezing, melting, evaporating, condensing, subliming and dissolving. If an object undergoes one of these processes, its form will return to its original form.
Meanwhile, changes in form still occur if the object undergoes changes that cannot return to its original form. Changes in permanent form are usually indicated by combustion and decay processes.
On this occasion, we will discuss further about dew or condensation. Usually, when the night air is very cold, dew will appear on the leaves in the morning. In fact, not a few people will play with the dew on the leaves. Dew itself is one of the properties of changing forms.
Condensation itself has another name, namely condensation. However, not many people know the condensation process. To find out, you can read this article.
Definition of Condensation
Condensation is a process of changing the state of an object to a denser form, such as gas (or steam) to liquid, a change in matter that releases heat. This condensation or condensation is the opposite of evaporation or evaporation which releases heat.
Apart from that, condensation occurs when water vapor in the air passes through a surface that is cooler than the dew point of the water vapor, this water vapor will condense into water droplets or dew.
According to the Big Indonesian Dictionary (KBBI), the meaning of the word condense is to become dew. Another meaning of condensation is to become water droplets (about steam). As previously explained, dew usually appears at night. This is in line with the definition of dew according to the KBBI, namely water droplets that fall from the air (especially at night).
Understanding Condensation According to Experts
Apart from the meaning of condensation or condensation according to the KBBI, several experts also express the meaning of condensation or condensation. Some experts also say that dew or condensation is difficult to separate from precipitation. The following is the definition of condensation according to experts, among others.
1. Wibowo et al (2016)
According to Wibowo, precipitation is an event where water falls from the atmosphere towards the earth’s surface. The form of liquid that falls can be snow, rain, fog and dew.
2. Triatmodjo (2008)
The definition of precipitation according to Triatmodjo is the descent of water from the atmosphere to the earth’s surface which can consist of dew, snow, hail and rain. For tropical areas, rain plays a big role or function. This is seen where it is usually not considered precipitation.
3. Karnaningroem (1990)
Karnaningroem said that the condensation process is a process of changing gaseous state to liquid state due to differences in temperature. The condensation temperature changes in line with the vapor pressure that occurs.
4. According to Research
The definition of precipitation according to researchers is any product of the condensation of water in the atmosphere. This occurs when the atmosphere becomes saturated and water then condenses and comes out of the solution (precipitates).
5. Quoted in the Natural Sciences Textbook in the Field of Business and Management Expertise
Condensation is a change in the state of a substance from gas to liquid. When the condensation process occurs, the gas releases heat (heat energy), so it turns into liquid.
Examples of Condensation in Everyday Life
Below are several examples of condensation in everyday life.
1. Condensation in the Morning
Condensation in the morning when we see wet leaves or grass even though there was no rain at night, water droplets or dew appear on the walls of the glass if the glass is filled with cold water. Condensation in a tent occurs due to the presence of water in the form of steam as a result of the breathing process.
The more crowded the condition of the tent, the more likely it is that condensation will occur due to respiratory vapor trapped in the tent walls. The formation of water droplets through condensation of water vapor in clouds. These water droplets will then fall in the form of rain.
2. Decrease in temperature at night
At night and in the morning, temperatures tend to cool down. Earth’s air contains water vapor in it. The more water vapor it contains, the more humid the air is. This causes water vapor that is suspended in the air to then experience condensation or condensation, producing dew drops.
3. Cloud and Rain Formation Process
Reporting from the US Geological Survey , clouds form in the atmosphere because air containing water vapor rises and cools. Water vapor in the form of gas rises into the atmosphere due to evaporation. High altitude in the atmosphere causes less pressure, indirectly lowering the air temperature.
As a result, the air temperature in the upper atmosphere is cooler than the temperature of the earth’s surface. When water vapor reaches the upper atmosphere, it then cools, turns into water droplets and forms clouds.
4. Water Drops on Cold Drinks
Cold drinks have a lower temperature than room temperature. When placed at room temperature, the water vapor in the air around the cold drink will condense and condense. The condensed water vapor changes form to water in liquid form.
This is the reason why canned drinks or cold drinks in glasses always drip with water. Not because the cold drink packaging leaked, but because the surrounding water vapor condensed.
5. Fog on Glasses
Foggy glasses are the use of glasses when eating warm food and drinks. This is because hot water vapor from food and drinks rises towards the face and meets cooler air. So, the water vapor condenses, forming small drops of water vapor. The drops of water vapor then stick to the glasses and make them foggy.
6. Fog on the car window
Foggy car windows are an example of an everyday event that indicates condensation is occurring. Reporting from Sciencing, the air in the car is warmer and contains a lot of warmer steam and contains a lot of water vapor from the passengers’ exhaled breath.
Meanwhile, car windows are cooler because they are influenced by wide air. The water vapor close to the car window then condenses, becoming fog that covers the car window.
7. Heated Sugarcane Molasses
8. Dew on Leaves
Water droplets (dew) on leaves in the morning. Even though it didn’t rain the night before, in the morning water droplets could be seen on the plants outside. The occurrence of dew in the morning helps the distillation process of certain substances.
9. Gas that becomes dew
The evaporated gas is flowed into a cold container, so that the gas turns into dew which then becomes alcoholic water.
10. Water Points on the Pan
There are water spots on the lid of the pan because the pan is hot.
11. Dew on the bathroom glass
The bathroom glass will water if exposed to hot water vapor.
When we see dew, we will definitely be very happy, especially as dew is believed to have many benefits, especially for eye health. Therefore, quite a few people drip dew into their eyes in the morning, are you one of them? Dew itself has several types, namely interior and exterior condensation.
