Multiple Choice

Attractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule are called

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

Multiple Choice

The fact that ice floats on liquid water is due to the fact that ........

• 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.

Multiple Choice

What property of water allows for water to act as a temperature regulator for the world?

• Cohesive Behavior

• Expansion Upon Freezing

• High Specific Heat

• Universal Solvent

Multiple Choice

• cohesion
• polar molecule
• hydrogen bond
• solution

Multiple Choice

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.

Multiple Choice
