Equal amount of water is poured into a glass, a bowl and a shallow dish, all made of stainless steel. All the three vessels are kept in the Sun. In which case evaporation will be faster and why? Explain the reasons in details. Draw Diagram. (5 marks)​

Answer 1

Explanation:

IN A BOWL THE EVAPORATION WILL BE FASTER

Answer 2

Answer

The water in the bowl will evaporate faster than the other two

━━━━━━━━━━━━━━━━

• Evaporation is a surface phenomenon that is, Evaporation depends on the surface area provide

• The tumbler doesn't provide as much as surface area as the bowl does

• Similarly the water needs surface area not shallowness and so the shallow dish no matter what it is made up of doesn't help

• Also Evaporation is dependent on wind, temperature, humidity of the environment etc...

• As the surface area increases there will be more particles that are exposed to the environment

• These cases like temperature, wind etc.. help those particles in gaining kinetic energy

• As they gain more and more kinetic energy they will be able to escape from the intermolecular force and become a vapour

• The more the surface are then more particles will be exposed to the environment and hence more Evaporation on the bowl
