Properties of Water

Front

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

Back

Water has a high heat capacity.

Front

When water sticks to itself, what is taking place?

Back

Cohesion

Front

Capillary action is the result of:

• adhesion
• cohesion
• change in matter (heat of fusion)
• both adhesion and cohesion

Back

both adhesion and cohesion

Front

Why does ice float?

Back

As water freezes, it expands and its density decreases.

Front

What property of water allows it to be such a versatile solvent that it is often called the "universal solvent?" Options: Purity,

Polarity

, High heat capacity, Expansion upon freezing

Back

Polarity

Front

Which end of the water molecule has a slightly positive charge? Options: the oxygen end, the hydrogen end, both ends are slightly positive, neither end is positive

Back

the hydrogen end

Front

The tightness across the surface of water that enables paper clips to float is ____________. Options: adhesion, capillary action, surface tension, polarity

Back

surface tension

Front

Which property of water allows it to form droplets when in liquid form?

Back

cohesion

Front

Which property of water enables it to move from the roots to the leaves of plants?

Back

Water exhibits capillarity.

Front

What might happen if water had a low specific heat instead of a high specific heat?

Back

Organisms that are sensitive to changes in temperature would die
