Which of the following occurs due to evaporation?
Which of the following occurs due to evaporation?
The correct option is A Drying of clothes
Explanation for correct option.
( A) Drying clothes.
The drying of clothes is an evaporation process. It is a slow process that involves the conversion of liquid to its vapor state. The rate of evaporation depends upon the following factors.
- Humidity- Low the humidity greater the evaporation.
- Wind- the faster the wind blows greater the evaporation rate.
- Temperature- as the temperature increases the rate of evaporation also increases.
- Surface area- Greater the surface area, the greater the evaporation rate.
Explanation for incorrect options.
(B) Burning of paper
Paper burning is chemical changes as ash forms in a new process and carbon oxide is also released during the process.
(C) Conversion of ice into water
Conversion of ice into water is a physical change, while heating ice converts it into liquid. Physical changes involve changes in the physical properties without altering their chemical composition. The process of conversion of solid into liquid is known as melting.
(D) Conversion of water into ice
Conversion of water into ice is a physical change, physical changes involve the change in the physical properties without altering its chemical composition. The conversion of liquid into ice is termed freezing
Hence option (A) is correct, drying of clothes.
