Question

The rate of evaporation increase with increasing:

• A. surface area
• B. temperature
• C. humidity
• D. wind speed

Answer 1

Answer: (A), (B), (D)

The correct options are
A surface area
B temperature
D wind speed

The rate of evaporation increases with increasing temperature, surface area and wind speed.

If temperature is increased, the kinetic energy of molecules will increase and more molecules will get converted into the vapour state.

With the increase in wind speed, the particles of water vapour move away with the wind, decreasing the amount of water vapour in the surrounding. As the surface area increases, more number of molecules will escape per unit time. The rate of evaporation depends on surface area because the bigger the area the more liquid is available to evaporate.

Hence options $A,B$ and $D$ are correct.
