How could water vapour contained in the air turn into liquid water? The answer to this question is ‘Condensation’. In CBSE Class 9 Chemistry, condensation appears in organic chemistry. It is nothing but a process in which a chemical reaction occurs while combining two or more molecules to form a single molecule. It usually happens within the loss of a small molecule, namely water. Therefore, it can be termed a dehydration synthesis if the water is lost.<\/span><\/p>\n

In this article, let us discover some of the facts and information regarding the condensation process in general while understanding the other related concepts.<\/span><\/p>\n

What is condensation?<\/h3>\n

In Class 9 Chemistry, condensation is explained by how vapours of water are converted into liquid. The main reason for this conversation is that there is a change in the substance\u2019s temperature and pressure.<\/span><\/p>\n

In detail, condensation is described as a chemical process that we tend to experience daily. For example, on a warm day, we can see that the mirror is fully covered with fog due to the temperature rise. Likewise, it is the same with taking a hot shower. Upon touching the mirror, we can notice that there will be small water beds on the mirror. This fog is because of condensation. Let us discuss it more in the upcoming passages.<\/span><\/p>\n

Condensation – Explanation<\/h3>\n

It is a fact that the condensation point and boiling point are the same. The occurrence of condensation will be at <\/span>100 \u2103<\/span>. While doing so, water will evaporate right after the temperature rises from the boiling point. In this case, it can be beyond <\/span>100 \u2103<\/span>. The water will boil and evaporate into the air, then form the water vapour.\u00a0<\/span><\/p>\n

Furthermore, if we reverse the process, i.e. when the water is cooled down to <\/span>10 \u2103<\/span>, the vapour will condense, turning back into its original liquid form. The condensation process occurs between the temperatures <\/span>0 \u2103 and 100 \u2103<\/span> or <\/span>32 \u2109 and 212 \u2109<\/span>.\u00a0<\/span><\/p>\n

One can notice it very well when there is a higher temperature difference between the atmosphere and the object. For instance, in ice candies, there will be a formation of droplets of water molecules when the temperature is hot.<\/span><\/p>\n

Condensation in the water cycle<\/h3>\n

The CBSE Chemistry students should know how condensation works in a water cycle. One of the key parts of the water cycle is condensation. Condensation is capable of showing how water is being cycled continuously throughout the earth’s liquid, solid, and gaseous forms.<\/span><\/p>\n

During the condensation process, water vapour will change into actual water in the form of fog, using moisture. Moreover, when there is a positive change in the altitude of the earth, there will be a decrease in the pressure and temperature of the earth, converting the vapours of water into liquid form.<\/span><\/p>\n

In addition, a large amount of concentration of these water droplets will form fog and cumulus clouds. After that, one can see that the water droplets get condensed, followed by falling on the earth’s surface as precipitation. This precipitation is commonly referred to as rain.<\/span><\/p>\n

Rain first enters the earth’s waterways, followed by entering the soil. After it gets into the soil, it will be absorbed by the plants, which will help them grow using photosynthesis. It is a process in which the plants absorb water, sunlight and carbon dioxide and emit oxygen.\u00a0<\/span><\/p>\n

Moreover, the water entering the soil will freeze to form a solid form. This solid form is commonly called ice. After doing so, it is capable of melting back into the water. This water can be utilised in all forms.<\/span><\/p>\n
