Question

question 30 (1 point) in this virtual lab experiment, how does the experiment demonstrate capillary action of water? a capillary action only happens in nonpolar molecules b water does not move in the tube, showing no interaction with surfaces c nonpolar liquids rise higher than water due to weaker bonds d water rises higher in narrow tubes because adhesion to the glass is stronger than cohesion alone question 31 (1 point) how does this virtual lab demonstrate the unique properties of water? a it proves that water molecules are nonpolar and do not interact strongly b it shows that hydrogen bonding gives water strong cohesion, adhesion, surface tension, and capillary action c it shows that water evaporates faster than nonpolar liquids because it has weaker bonds d it demonstrates that water has no intermolecular forces and cannot climb in capillary tubes

Explanation:

Capillary action in water occurs because the adhesion of water to the glass surface is stronger than the cohesion within water molecules, causing water to rise higher in narrow tubes. Hydrogen - bonding in water gives it strong cohesion, adhesion, surface tension, and enables capillary action.

Answer:

Question 30: d. Water rises higher in narrow tubes because adhesion to the glass is stronger than cohesion alone
Question 31: b. It shows that hydrogen bonding gives water strong cohesion, adhesion, surface tension, and capillary action
