What is the primary reason for the phenomenon of capillarity?
Correct Answer: Surface tension
- Step 1: Understand that capillarity is the ability of a liquid to move in narrow spaces.
- Step 2: Recognize that this movement can happen against the force of gravity.
- Step 3: Learn that surface tension is a force that acts on the surface of a liquid.
- Step 4: Realize that surface tension is caused by the attraction between the molecules of the liquid.
- Step 5: Conclude that surface tension is the primary reason why liquids can rise or fall in narrow spaces, leading to capillarity.
