Properties of Water

Front

Which property of water enables it to move from the roots to the leaves of plants? Options: Water expands as it freezes., Water is an excellent solvent., Water exhibits cohesive behavior., Water is able to moderate temperature.

Back

Water exhibits cohesive behavior.

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

Why does ice stay at the top of oceans instead of sinking to the bottom? Options: Ice is colder than liquid water, Ice is less dense than liquid water, Ice is more dense than liquid water, Ice is warmer than liquid water.

Back

Ice is less dense than liquid water.

Front

What property of water allows it to be a versatile solvent? Options: purity, polarity and cohesion, high heat capacity, expansion upon freezing

Back

polarity and cohesion

Front

Why can small insects walk across the surface of calm water?

Back

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

Front

What process helped the carnations to change color when placed in water with blue dye?

Back

Cohesion and adhesion of water molecules

Front

Which property of water makes it good at regulating temperature?

Back

Water has a high capacity for heat.

Front

What might happen if water had a low specific heat instead of a high specific heat? Options: Flooding would occur and animals would be forced to migrate, Harmful organisms living in water would reproduce at a rapid rate, Organisms that are sensitive to changes in temperature would die, Plants would not have enough water to effectively carry out photosynthesis.

Back

Organisms that are sensitive to changes in temperature would die

Front

What unique property of water allows fish and aquatic plants to survive a cold winter by preventing a lake from freezing solid?

Back

Water expands and becomes less dense when it freezes.

Front

Which of the following characteristics of water is not a result of hydrogen bonding? Options: adhesive strength, capillarity, cohesive strength, All of the above are a result of hydrogen bonding.

Back

All of the above are a result of hydrogen bonding.
