Properties of Water

Front

What does it mean if a molecule is polar?

Back

It means the charges are on opposite sides of the molecule.

Front

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

Back

The hydrogen end.

Front

What happens to the rate of solute dissolution when the temperature increases?

Back

It increases the rate of dissolution.

Front

Why can water striders walk across the surface of water without falling through?

Back

They are light enough so they don't break the hydrogen bonds holding the water molecules together.

Front

What property of water allows it to stick to other substances?

Back

Adhesion.

Front

What is cohesion in relation to water?

Back

Cohesion is the property that allows water molecules to stick to each other due to hydrogen bonding.

Front

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of a substance by one degree Celsius.

Front

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

Back

It helps regulate temperature in the environment, preventing drastic temperature changes.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of a liquid that makes it behave like a stretched elastic membrane.
