How does capillary action allow water to climb up the sides of a straw? (For biology homework, please help if you can)

What transpires inside a drinking straw that has been placed in a cup of water is an illustration of capillary action.

The water will rise inside the straw a little bit higher than the rest of the water because the force of adhesion holding the water together and to the straw is a little stronger than gravity.

  • The adhesion of water molecules to other molecules, or the attraction between them, is also connected to these cohesive forces.
  • This may be seen when a straw is placed in a glass of water and water "climbs" up the straw. You'll see that the water seems to be higher on the straw's sides than in the center.
  • When we suck from a straw, a low-pressure area is generated inside our lungs by increasing the capacity of our lungs.
  • As a result, the liquid rises inside the straw as a result of the atmospheric pressure forcing it into our mouth from the outside.
