Question

Measure 200 mL of water and pour it in an open vessel. Now, take 200 mL of water and pour it in another narrow vessel. Keep both on the flame and note the time taken for complete evaporation of water.

Observation : Vessel ______ has more surface area so the water will evaporate at a faster rate than the water in vessel_______​

Answer 1

Answer:

Vessel 1st (open vessel) has more surface area so the water will evaporate at a faster rate than the water in vessel 2nd (narrow vessel)

Explanation:

If the surface area is increased, then the amount of liquid that is exposed to air is larger. If more area 8s exposed to air, allowing water molecules acquire more heat energy from surrounding. Due to the increased heat energy (kinetic energy), there is more rPid movement of the water molecules which held them to overcome the force of attraction and evaporate.
