When a cylindrical tube is dipped vertically into a liquid the angle of contact is

{140^\mathrm{o}}

, when the tube is dipped with an in inclination of

{40^ \circ }

the angle of contact is

View answer and explanation

Correct option: B

{140^ \circ }

Option B is correct because the angle of contact is a property of the liquid and the tube material and does not depend on the inclination of the tube.

With the increase in temperature viscosity of a liquid - Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.

Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.

In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
