Question

20. Water in a dish evaporates faster than in a bottle.
Give reason.

Answer 1

Answer:

Greater the surface area, greater is the rate of evaporation and since, water in a dish has greater surface area than in a bottle thus, it evaporates faster.

Answer 2

Evaporation is a surface phenomena i.e more the exposed surface area more is rate of evapouration. The water in a dish evaporates faster than in a bottle because the surface area of the dish is larger than the surface area of bottle.
