Water Properties

Front

What is the unique property of water that allows ice to float on liquid water?

Back

As water freezes, it expands and its density decreases.

Front

What is the reason a water strider can skate along the top of a pond?

Back

Hydrogen bonds result in water surface tension by cohesion.

Front

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

Back

The hydrogen end.

Front

What is the effect of the low density of frozen water in a lake?

Back

When water in a lake freezes, it floats, providing insulation for organisms below.

Front

Which of the following is NOT a unique property of water?

Back

Water cools very rapidly.

Front

What is cohesion in the context of water properties?

Back

Cohesion refers to the attraction between water molecules due to hydrogen bonding.

Front

What is adhesion in the context of water properties?

Back

Adhesion is the attraction between water molecules and other substances.

Front

How does water's high specific heat affect the environment?

Back

Water can absorb and store large amounts of heat, moderating temperature changes in the environment.

Front

What role do hydrogen bonds play in water's properties?

Back

Hydrogen bonds contribute to water's cohesion, adhesion, high specific heat, and surface tension.

Front

Why is water considered a universal solvent?

Back

Water can dissolve many substances due to its polar nature.
