Question

Explain the factor of evaporation.

Answer 1

Factors That Affect Vaporization

The main factors that have an effect on vaporization are as follows :

Vaporization increases with an increase in the surface area.It increases with an increase in temperature.Vaporization increases with the decrease in humidity.It increases with increase in wind speed.

Evaporation increases with an increase in the surface area

If the surface area is increased, then the amount is of liquid that is exposed to air is larger. More molecules can escape with a wider surface area. For e.g. We spread out clothes to dry. We do that because that speeds up the process of vaporization.

Evaporation increases with an increase in temperature

The water molecules move rapidly when the water is heated. This makes the molecules escape faster. Higher temperatures lead to increase in vaporization as more molecules get kinetic energy to convert into vapor. For example, boiling water evaporates faster than fresh tap water.

Evaporation increases with a decrease in humidity 

Humidity means the amount of vapor present in the air. The air around can only hold a certain amount of vapor at a certain time and certain temperature. If the temperature increases and the wind speed and humidity stay constant, then the rate of evaporation will increase since warmer air can hold more water vapor than colder air.

Evaporation increases with an increase in the speed of wind 

Particles of vapor move away when the speed of wind increases. This leads to a decrease in the amount of water vapor in the atmosphere. For example, we use hand dryers to dry our hands. Here the wind is expelled from the hand dryer which dries our hand.
