24-25 Quiz Water Properties

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

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

Why does ice float?

• As water freezes, it expands and becomes less dense.

• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, it becomes nonpolar and no longer mixes with the liquid.

• 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...

• can be found anywhere

• freezes when it gets cold

• floats when frozen
• dissolves most substances

Large bodies of water, such as lakes and oceans, do not quickly change in temperature. What is the reason for this?

• Water is an acid.
• Water is a versatile solvent.
• Water has a high heat capacity.
•  Water acts as a buffer.

Which of these is NOT an example of water being beneficial and helping to maintain homeostasis in living things?

• Temperature regulation in humans due to sweating

• Universal solvent so nutrients can be absorbed into cells

• Insulates lakes when frozen so animals and plants can survive winter

• Ocean pH being extremely acidic which can dissolve shells

The ability of water molecules to stick to each other, creating surface tension is called:

• Cohesion

• Adhesion

• Specific Heat Capacity

• pH

Which one of these substances will have a NEUTRAL pH?

• Lemon juice

• Coffee

• Bleach

• Water

• oil

• sugar

• salt

• all of these
