140.
What property of water helps to moderate earth's temperature?
a)
adhesion
b)
chohesion
c)
Specific heat capacity
d)
Latent heat of vaporization
141.
Which is NOT a unique property of water?
a)
Frozen water floats on liquid water.
b)
Water covers most of the Earth’s surface and retains a large amount of heat.
c)
Water molecules stick to each other through hydrogen bonds.
d)
Water cools very rapidly.
142.
Attractions between water molecules are called
a)
Covalent bonds
b)
Ionic bonds
c)
Polar bonds
d)
Hydrogen bonds
143.
Why does water move from the roots to the leaves of plants?
a)
Water is pushed by solutes
b)
Capillary action pulls the water molecules like a chain
c)
Water is pulled by gravity
d)
Water’s cohesion causes it to “pull” towards the leaves
144.
What word describes when water is attracted to other substances?
a)
cohesion
b)
adhesion
c)
capillary action
d)
surface tension
145.
What two elements make up water?
a)
Helium and oxygen
b)
Hydrogen and oxygen
c)
helium and carbon
d)
oxygen and carbon
146.
Water striders can walk across the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?
a)
The insects are light enough so they do not break the hydrogen bonds holding the water molecules together
b)
The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.
c)
The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
d)
The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
147.
Large bodies of water do not quickly fluctuate in temperature. Why?
a)
Water is a solvent.
b)
Water has a high heat capacity.
c)
Water acts as a buffer.
d)
Water is non-polar.
148.
What property of water allows it to be such a versatile solvent that it is often called the "universal solvent?"
a)
Purity
b)
Polarity and cohesion
c)
High heat capacity
d)
Expansion upon freezing
