Assertion (A) Liquids tend to have the maximum number of molecules at their surface.
Reason (R) Small liquid drops have spherical shape.
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true but R is the correct explanation of A
(c) A is true but R is false
(d) A is false but R is true
In the following question a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct option out of the choices given below in each question.
Assertion (A) Liquids tend to have the maximum number of molecules at their surface.
Reason (R) Small liquid drops have spherical shape.
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true but R is the correct explanation of A
(c) A is true but R is false
(d) A is false but R is true
Answer: (d) A is false but R is true
The assertion is false but the reason is true.
Liquid tends to acquire a minimum surface area due to surface tension. Thus, small liquid drops are spherical. In spherical shape, the surface area is minimum, that's why small liquid drops have the spherical shape.
