If the surface of a liquid is plane, then the angle of contact of the liquid with the walls of container is
1 Acute angle
2 Obtuse angle
3 \(90^{\circ}\)
4 \(0^{\circ}\)
Explanation:
Tangent drawn at point of contact makes \(90^{\circ}\) with wall of container.

Statement A : The angle of contact of a liquid with a solid increases with increase in temperature of liquid. Statement B : With increase in temperature, the surface tension of the liquid decreases.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Angle of contact increases with increase in temperature. The surface tension of a liquid decreases with increase in temperature. So option (3) is correct.

If the angle of contact is less than \(90^{\circ}\) the pressure just inside the surface of a meniscus
1 is less than atmospheric pressure
2 is greater than atmospheric pressure
3 is same as the atmospheric pressure
4 None of the above

When the temperature is increased the angle of contact of a liquid
1 Decreases
2 Increases
3 First increases and then decreases
4 Remains the same
Explanation:
Cohesive force decreases so angle of contact decreases.
