Answer 2

Evaporation is the process in which a liquid state of matter (water) is converted into a gaseous state of matter (vapour). In general terms, evaporation is defined as the process in which the liquid state is converted into gas. This process requires heat energy.

Factors That Affect the Evaporation

Temperature

• As the temperature increases, the rate of evaporation also increases. Temperature and rate of evaporation are proportional to each other.

Surface area

• As the surface area increases, the rate of evaporation increases. The surface area and rate of evaporation are proportional to each other.

Humidity

• The rate of evaporation decreases with an increase in humidity. Humidity and the rate of evaporation are inversely proportional to each other.

Wind speed

• Increase in wind speed results in increased evaporation. Wind speed and rate of evaporation are proportional to each other.

Examples of Evaporation

• Crystallization
• Drying of clothes
