Question

1 multiple choice 1 point which property of water allows it to form large droplets on a penny without immediately spilling over? adhesion cohesion solubility capillary action 2 multiple choice 1 point which molecular force is mainly responsible for waters high surface tension? ionic bonding metallic bonding hydrogen bonding covalent bonding 3 multiple choice 1 point water rises higher in a thin glass tube than other liquids. this is an example of: capillary action surface tension vapor pressure density differences

Explanation:

For question 1:

• Adhesion is the attraction between different substances.
• Cohesion is the attraction between like - water molecules. This allows water to form droplets as water molecules stick to each other.
• Solubility is about a substance dissolving in another.
• Capillary action involves movement in narrow spaces due to adhesion and cohesion but is more about movement in tubes.

For question 2:

• Ionic bonding is between ions.
• Metallic bonding is in metals.
• Hydrogen bonding in water (between the hydrogen of one water molecule and the oxygen of another) creates strong intermolecular forces, which contribute to high surface tension.
• Covalent bonding is within the water molecule (O - H bonds), not the intermolecular force responsible for surface tension.

For question 3:

• Capillary action is the ability of a liquid to flow in narrow spaces without the help of, or even in opposition to, external forces like gravity. Water rising in a thin glass tube is a classic example of capillary action due to the combination of adhesion (water to glass) and cohesion (water to water).
• Surface tension is the "skin - like" property of the surface of a liquid.
• Vapor pressure is related to the tendency of a liquid to evaporate.
• Density differences are about mass per unit volume and not related to this rising phenomenon.

Answer:

1. B. Cohesion
2. C. Hydrogen Bonding
3. A. Capillary Action
