Which of the following phenomena does not involve surface tension?

AMercury drops acquire spherical shape
BLiquids tend to rise in the capillary
CA liquid flows over a fixed surface
Correct Answer
DMoist soil grains are pulled togther

Solution

Examples of phenomena involves surface tension are :
$$1.$$ Spherical shape acquired by mercury droplets.
$$2.$$ Liquid tending to rise in capillary tube.
$$3.$$ Moist soil grains are pulled together.
The phenomena involved in a liquid flowing over a fixed surface is viscocity of fluids.
