Question

Washed clothes dry up more quickly on a hot summer day than on a rainy day . why ?

Answer 1

washed clothes dry up more quickly on a hot summer day than on a rainy day because evaporation is dependent upon the increase in surface area, increase in temperature and increase in wind speed. Therefore, when the clothes are washed, they dry up faster.

Answer 2

Rate of evaporation depends on 4 factors:
1. Temperature.
2. Wind speed.
3. Surface area.
4. Relative Humidity.
PART 1: So, The relation between Rate of evaporation and Temperature is "Directly proportional"
Hence, as on a hot day, Temperature is high, so, rate of evaporation is faster.
HENCE, THE WATER EVAPORATES FROM THE CLOTHES FASTER.

PART 2: On a rainy day, The Humidity, too affects the rate of evaporation.
