Properties of Water Review

Water can hold a great deal of heat and help moderate the climate of a nearby landmass because of which property?

• specific heat (high heat capacity)

• cohesion

• adhesion

• polarity

Attractions between water molecules are called

• Covalent bonds

• Ionic bonds

• Polar bonds

• Hydrogen bonds

Water is a universal solvent because it...

• It can be found anywhere

• It freezes when it gets cold

• floats when frozen

• Dissolves most substances

Why can fish survive winters in a pond?

• ice is less dense than liquid water so it will be on the top of a lake or pond allowing fish to swim beneath it

• water is available in all 3 phases so ice will be on the top of a lake or pond allowing fish to swim beneath it

• water is polar so ice will be on the top of a lake or pond allowing fish to swim beneath it

• Adhesion so ice will be on the top of a lake or pond allowing fish to swim beneath it

Water has a high specific heat which means it can hold a great deal of thermal energy without rapidly increasing in temperature. What will this affect?

• Cities that are close to Oceans and large lakes

• Cities that are near ponds or rivers

• Deserts far from oceans

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

• Water is pushed by solutes

• Capillary action pulls the water molecules like a chain

• Water is pulled by gravity

• Water’s cohesion causes it to “pull” towards the leaves

Refer to the picture; this is occurring because of:

• Adhesion

• Cohesion

Refer to the picture; this is occurring due to:

• Adhesion

• Cohesion

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.

Small insects can walk across the surface of calm water. Their feet push the surface of the water down slightly, somewhat like a person walking across a trampoline, but they do not break the surface. What is the best explanation for why this happens?

• The insects are light enough so that they do not break the hydrogen bonds holding the water molecules together

• The insects actually use their wings to hover slightly above the water's surface and they only skim it with their feet

• The insects' feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water's surface

• The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
