Question

Answer the question:
Puddles of rain water remain after a storm. The water in the puddles gradually evaporates.
How does the evaporation affect the temperature of the water remaining in the puddle, and how does it affect the average speed of the remaining water molecules in the puddles ?
temperature of water in puddleaverage speed of water molecules in puddle
Adecreasesdecreases
Bdecreasesincreases
Cincreasesdecreases
Dincreasesincreases

Solution
Verified by Toppr

Evaporation is the process of losing heat through the conversion of water to gas.
So Temperature of water in puddle decreases and speed of molecule also decreases as it is proportional to temerature.
so option A is correct.
