Given below are two statements : Statement I : When a capillary tube is dipped into a liquid, the liquid neither rises nor falls in the capillary. The contact angle may be 0^ . Statement II : The contact angle between a solid and a liquid is a property of the material of the solid and liquid as well. In the light of the above statement, choose the correct answer from the options given below.

Options

  1. ABoth Statement I and Statement II are false
  2. BBoth Statement I and Statement II are true
  3. CStatement I is false but Statement II is true
  4. DStatement I is true and Statement II is false

Correct answer

C. Statement I is false but Statement II is true

Step-by-step solution

Capillary rise h = 2 ~T gr ; If =0^ then rise is non-zero Statement-1 is incorrect.
