Question

What is Condensation​

Answer 1

Answer:

Condensation refers to the process of water vapour changing into liquid water. In other words, the water present in the air i.e. water vapour cooled down when it came in contact with your mirror’s surface after the hot shower. This resulted in the vapour condensing or turning into a liquid form. Thereon, you will notice moisture or water beads plus fog which was in the mirror.

Therefore, condensation is a change in the state of water from a gas in a liquid form. It takes place when the vapour in the warm air meets a cool surface. However, it does not necessarily require a solid surface. To simplify it, just think of condensation as the opposite of evaporation.

Process of Condensation

Just like any other matter, water also consists of molecules. The molecules are energetic, fast-moving and far apart when they are in the form of vapour. Thus, when this vapor bumps into cooler temperatures, they become the opposite. That is, they get slower, lesser energetic and drift closer. Subsequently, the vapour turns into liquid upon reaching a threshold energy level.

Anyone can demonstrate the process of condensation through an easy experiment. You will require a cup and water. Fill a cup nearly two-thirds full of hot water. Take one more cup, flip it upside down, and put it on top of the cup with hot water. Then put an ice cube on top of the upside-down cup.

Condensation will start to form at the top of the upside-down cup, just like a cloud. Therefore, you can try out this experiment at home with kids to make them understand this phenomenon in a better and effective manner.

Answer 2

$\huge\underline\mathrm\red{Answer}$

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
