Question

The temperature at which a gas is converted into a liquid is called its condensation point.
A. True
B. False

Answer 1

Hint: Matter exists in three states; solid, liquid and gas. The process of conversion of matter from gaseous state to liquid is known as condensation. Condensation can occur by change in pressure and/or temperature of the substance.
The condensation point of water is ${{100}^{{}^\circ }}C$.

Complete answer:
 Matter is considered to exist mainly in three states namely, solid liquid and gas. When state of matter changes, a phase change is said to have occurred.
We often see water droplets on a glass filled with chilled water. From where do these droplets come? Actually, water vapours present in the atmosphere around the glass are condensed to form water droplets. Condensation is a phenomenon of a substance in a gaseous state converting into a liquid state. The change in state can be brought by change in pressure and temperature of the substance.
The temperature at which a gas is converted into a liquid is called its condensation point.

So, the correct answer is “Option A”.

Additional Information:
Condensation plays an important role in the water cycle. During the process of condensation, water vapours present in air are converted to liquid water. When the altitude increases, the pressure and temperature both decreases, which cause water vapour to convert into liquid water droplets.
When a large number of droplets condense, they form clouds and fog. When these water droplets fall on earth as precipitation, it is known as rain. This rain water goes to water sources like lakes, sea etc. The next step is the evaporation of water from water sources which cause liquid water to convert into vapours. And the process continues to repeat.

Note:
The temperature at which a gas is converted into a liquid is called its condensation point. The condensation point of water is same as the boiling point of water i.e. ${{100}^{{}^\circ }}C$
The process through which water vapour present in air is converted into liquid water is known as condensation. Condensation is a process opposite to evaporation.
