Question

State whether the given statement is true or false
Evaporation takes place at all temperatures.
(A) True
(B) False

Answer 1

Hint: Evaporation is a very common phenomenon which takes place around us. The process of evaporation is an important part of the water cycle process.

Complete step by step answer:
Evaporation is the process by which water changes from a liquid to a gas. It is an invisible process. The presence of moisture in the atmosphere is due to the process of evaporation from water bodies. Heat is necessary for the process of evaporation to take place. Heat is needed to break the bond between the hydrogen and oxygen molecules. Evaporation as a result takes place at all temperatures. Hence the given statement is true.

Additional information:
Due to evaporation heat is removed from the environment during evaporation, leading to a net cooling. In fact, the process of evaporation removes heat from the environment. Water is evaporating, but staying in the air as a vapor. Once water evaporates, it also helps in the formation clouds.

Note:During the process of evaporation the molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Heat from the sun drives the evaporation process. Many factors affect the evaporation process and when the humidity is 100%, the air is saturated with water. No more water can evaporate. Air pressure also affects evaporation. Temperature affects how quickly evaporation will happen. Evaporation is just the opposite of condensation, which is the process of water vapor turning into liquid water.
