Detailed explanation-1: -For example, capillary actions works when placing a thin or narrow straw into a cup of water, we can see the water goes into the straw; the level the water reaches in the narrow straw is higher than the surrounding water in the cup.

Detailed explanation-2: -Examples of capillary action include the uptake of water in paper and plaster (two porous materials), the wicking of paint between the hairs of a paintbrush, and the movement of water through sand.

Detailed explanation-3: -An example of capillary action is what happens inside a drinking straw left in a cup of water. The force of adhesion which holds the water together and to the straw is a little stronger than gravity, so the water will rise inside the straw a little higher than the rest of the water.

Detailed explanation-4: -Plants use capillary action to bring water up the roots and stems to the rest of the plant. The molecules of the water (the liquid) are attracted to the molecules of the inside of the stem (the solid). This attraction is used to help force the water up from the ground and disperse it throughout the plant.
