Question

1)Assertion(A):Rate of evaporation of water in a plate is higher than in a cup
Reason(R):Rate of evaporation decrease with increase in humidity
a)Both A and R are true and R is the correct expalnation of the assertion
b)Both A and R are true but R is not the correct expanation of the assertion
c)A is true but R is false
d)A is false but R is true

Answer 1

Assertion(A):Rate of evaporation of water in a plate is higher than in a cup

Assertion(A):Rate of evaporation of water in a plate is higher than in a cupReason(R):Rate of evaporation decrease with increase in humidity

→b) Both A and R are true but R is not the correct explanation of the assertion

____

correct explanation of assertion↓

because surface area affects the rate of evaporation , when surface area is increased , more particles of water get space to go into vapour state.
