AP: Properties of water

What is a hydrogen bond?

• attraction of a slightly positive hydrogen to a slightly negative atom in the vicinity.

• attraction of a slightly negative hydrogen to a slightly positive atom in the vicinity.

• repulsion of a slightly positive hydrogen to a slightly negative atom in the vicinity.

• repulsion of a slightly negative hydrogen to a slightly positive atom in the vicinity.

What two elements make up water?

• Hydrogen and oxygen
• helium and carbon
• oxygen and carbon

Attractions between water molecules are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds

What is the correct definition for cohesion?

• ability of water molecules to cling to other polar surfaces.

• ability of water molecules to cling to each other due to hydrogen bonding.

• ability of water molecules to cling to other non polar surfaces.

• ability of water molecules to cling to each other due to covalent bonding.

What actions contribute to the transport of water in plants?

• Cohesion and Adhesion

• Surface Tension and Adhesion

• Cohesion and Surface Tension

• Dehydration and Adhesion

A water strider can skate along the top of a pond because:

• covalent bonds result in water cohesion
• hydrogen bonds result in water cohesion (surface tension)
• water striders have adapted to take advantage of water cohesion
• low surface tension of water

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

The attraction that causes water and other liquids to form drops on thin films is called ________________. This is also water’s ability to be attraction to other water molecules.

• adhesion
• capillary action
• cohesion
• surface tension

Why does ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances
