SUMMARY

The discussion centers on the capillary action observed when a paper towel connects a full glass of water to an empty glass. The water rises through the paper towel due to its absorbent properties, which are attributed to the structure of cellulose fibers that create small spaces for water to travel. This phenomenon occurs until the water levels in both glasses equalize, demonstrating the balance of forces between gravity and surface tension. The process is governed by principles of fluid dynamics and adhesion.

PREREQUISITES
  • Understanding of capillary action
  • Familiarity with fluid dynamics
  • Knowledge of surface tension
  • Basic concepts of adhesion and cohesion
NEXT STEPS
  • Research the principles of capillary action in liquids
  • Study the molecular structure of cellulose and its impact on absorbency
  • Explore fluid dynamics and the forces acting on liquids
  • Investigate the role of surface tension in liquid behavior
USEFUL FOR

Students in physics or chemistry, educators explaining fluid dynamics, and anyone interested in the science behind everyday phenomena like water movement in absorbent materials.

Hello.
I have a question.
I have two glasses - one is full, one is empty. And I will take a long paper towel to them - the first end to full glass and the second end to empty glass to same height.
A paper towel is absorbent. Water from full glass rises to empty glass. It will stop when the height of watter will be in glasses same, yeah? However, can you tell me why? Why is paper towel absorbent? What is structure of paper towel's? Why wather rises to empty glass? How it to overcome gravity? And why it will stop when the height of water i in bother glass same?
Pls, explain me it, i really want to understant it.
