Given below are two statements : Statement I : The contact angle...
Given below are two statements :
Statement I : The contact angle between a solid and a liquid is a property of the material of the solid and liquid as well.
Statement II : The rise of a liquid in a capillary tube does not depend on the inner radius of the tube.
In the light of the above statements, choose the correct answer from the options given below:
Options
- AStatement I is true but Statement II is false.
- BStatement I is false but Statement II is true.
- CBoth Statement I and Statement II are false.
- DBoth Statement I and Statement II are true.
Correct answer
A. Statement I is true but Statement II is false.
Step-by-step solution
Statement I is correct as we know contact angle depends on cohesine and adhesive forces.
Statement II is incorrect because height of liquid is given by where is radius of Tube (assuming length of capillary is sufficient).
