Question

While putting clothes for drying up, why do we spread them out?

• A. Surface area is directly proportional to rate of evaporation.
• B. Increase in surface area decreases rate of evaporation.
• C. Increase in surface area increases rate of evaporation.
• D. Both A and C.

Answer 1

The correct option is D Both A and C.

Evaporation is a surface phenomenon. If the surface area is increased, the rate of evaporation increases. While putting clothes for drying up, we spread them out, because, more area is exposed to sun and wind which speeds up the rate of evaporation.
