Question

what is capillary effect explain through some examples.

Answer 1

A combination of adhesive and cohesive forces accounts for capillary action, which is the tendency of water to move in narrow tubes, even against the force of gravity. For example, water moves through the microscopic spaces between soil particles to the roots of plants by capillary action. Plants depend on capillary action to transport water and nutrients, and sponges and paper towels use capillary action to absorb spilled fluids. Capillary tubes are often used to draw small samples of blood from a needle prick in the skin.
