Question

a student carefully pours water down a string from a cup on the counter to a cup on the floor. the water molecules that travel along the string are exhibiting _________.
adhesion and cohesion
electronegativity
solubility
capillary action

Explanation:

Adhesion is the attraction between different substances (water - string), and cohesion is the attraction between water molecules themselves. Capillary action, which relies on adhesion and cohesion, allows water to travel along the string. Electronegativity refers to an atom's ability to attract electrons in a chemical bond and is not relevant here. Solubility is about a substance dissolving in a solvent, which is not what's happening as water travels along the string. So the water molecules are exhibiting adhesion and cohesion and capillary action.

Answer:

A. adhesion and cohesion, D. capillary action
