Properties of Water

Which end of the water molecule has a slightly positive charge?

• the oxygen end
• the hydrogen end
• both ends are slightly positive
• neither end is positive

Which of the following is LEAST likely to dissolve in water?

• nonpolar fats and oils
• polar sugar molecules
• salt made of a positive sodium ion and a negative chloride ion
• all of the substances will dissolve easily in water

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

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

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

Which of the following interactions are taking place at the dotted lines in the diagram?

• Polar covalent bonds

• Intermolecular force

• Ionic bonds

• Hydrogen bonds
• Electrostatic force

Why does water move from the roots to the leaves of plants?

• Solutes push the water up the plant.

• Capillary action pulls the water molecules like a chain against gravity.

• Water is pulled by gravity through the plant body.

• The high specific heat of water allows water to move freely through the plant.
