Question

The rate of evaporation depends on _____
A. Surface area
B. Temperature
C. Humidity
D. All of the above

Answer 1

Hint:The evaporation is the technique by which the liquid changes its state to gaseous by heating the liquid to its boiling point temperature. This question contains more than one correct option.

Complete step by step answer:
The evaporation is the method by which the compound in liquid state changes to vapor by heating the water to its boiling point.
The rate of evaporation depends on various factors which are given below.
(1) Temperature: When we increase the temperature of the liquid, it results in the increase of the kinetic energy of the molecules present in the liquid. By increasing the energy, the liquid molecules overcome the intermolecular force of attraction and escape in the form of gas in the atmosphere. Thus, the greater is the temperature of the liquid, faster will be the rate of evaporation.
(2) Surface area: Evaporation takes place on the surface of the liquid. During the evaporation process, the molecules present on the surface overcome the intermolecular force of attraction and break away from the liquid particles and skip to the environment. Thus, greater is the surface area occupied, evaporation will take place quickly.
(3) Humidity: The greater is the humidity of the atmosphere which is surrounding the water molecule, the rate of evaporation is slow.
Thus, the rate of evaporation depends on the surface area, temperature and humidity.
Therefore, the correct option is D.

Note:
The surrounding temperature also contributes to the increase in the rate of evaporation as hot environment can easily transfer its heat to the liquid. The air circulation and wind speed also affect the rate of reaction.
