Question

4.Why do wet clothes dry faster in the sun than in shade?
5. Why do wet clothes dry faster when spread in open?
6. Why should we wear cotton clothes during summers?
7. Is evaporation an exothermic or endothermic process?​

Answer 1

Answer:

4) because they gain more energy from sun and evaporate easily .

5) because as surface area increases evaporation also increases .

6)cotton clothe are light colored and light in weight and being porous they absorb sweat and expose it to environment and make us feel cool by latent heat of evaporation.

7) endothermic process as it gains energy and converts water into vapour.

Explanation:

HOPE THIS HELPS

Answer 2

Answer:

4. because sun transfers the heat to the cloth molecules. then they carry heat upwards.

5. because they get more surface area

6. because cotton clothes do not trap heat and sweat and allow air to pass

7. exothermic reaction (evaporation carries latent heat upwards)
