Question

1. how does capillary action allow water to climb up the sides of a straw? 13. a mixture that forms when one substance dissolves another is called a(n) ________. the substance that does the dissolving is called a(n) ________. 14. why can water dissolve many substances?

Explanation:

1. Capillary action is due to adhesion (attraction between water and the straw - side molecules) and cohesion (attraction between water molecules). Adhesion pulls water up the sides and cohesion allows the water column to stay together.
2. In a solution, the substance that dissolves another is the solvent and the dissolved substance is the solute.
3. Water can dissolve many substances because it is a polar molecule. The positive and negative ends of water molecules can attract and surround ions and polar molecules of other substances, breaking them apart and dissolving them.

Answer:

1. Capillary action is a result of adhesion and cohesion.
2. Solvent; Solute
3. Water is a polar molecule, so it can attract and surround ions and polar molecules of other substances to dissolve them.
