Water can easily rise in capillaries due to the following EXCEPT __________.
Options
- Ahigh surface tension
- Bhigh specific heat
- Chigh adhesive force
- Dhigh cohesive force
Correct answer
B. high specific heat
Step-by-step solution
Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity. It is a result of intermolecular forces.
The rise of water in a capillary tube is governed by the formula , where is the surface tension and is the angle of contact.
Surface tension arises due to high cohesive forces between water molecules. The angle of contact depends on the relative strength of adhesive forces (between water and the capillary wall) and cohesive forces.
High surface tension, high adhesive forces, and high cohesive forces all contribute to the capillary rise of water.
High specific heat is a thermal property that determines the amount of heat required to raise the temperature of water. It has no role in capillary action.
