Question

Assertion (A): Liquids tend to have maximum number of molecules at their surface.

Reason (R): Small liquid drops have spherical shape.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A

• A is true but R is false.

• A is false but R is true.

Answer 1

A is false but R is true.

Explanation:

Liquid tends to minimise the number of molecules at their surface due to surface tension; this leads to the spherical shape of small liquid drops.
