Understanding Cohesion and Adhesion through a Simple Experiment

What materials are required to set up the experiment?

• Two strings, a cup, and a tape

• A string, a cup, and a spoon

• A string, two cups, and a tape

• A string, two cups, and a spoon

What is the purpose of moistening the string in the experiment?

• To make the string longer

• To make the string heavier

• To allow water molecules to stick to it

• To change the color of the string

What is the role of cohesion in the experiment?

• It causes water to evaporate

• It makes water molecules stick to the string

• It makes water molecules stick to each other

• It changes the color of the water

How does adhesion contribute to the experiment?

• It prevents water from flowing

• It causes water to evaporate

• It makes water molecules stick to the string

• It changes the color of the water

What prevents the water from dripping straight down in the experiment?

• The color of the water

• Cohesion and adhesion

• The length of the string

• The weight of the water
