Basic Chem and Water Properties Review Quiz

Water can hold a great deal of heat and help moderate the climate of a nearby landmass because of which property?

• specific heat (high heat capacity)

• cohesion (sticking to like molecules)

• adhesion (sticking to unlike molecules)

• polarity (oppositely charged regions)

Which answer describes COHESION.

• Water molecules attracted to other substances.

• Water molecules climbing upwards against the force of gravity.

• Water molecules dissolving many substances because of its polarity.

• Water molecules attracted to other water molecules.

Describe ADHESION.

• Water molecules attracted to other substances.

• Water molecules climbing upwards against the force of gravity.

• Water molecules dissolving many substances because of its polarity.

• Water molecules attracted to other water molecules.

Surface tension is caused by ...

• strong cohesion between water molecules
• strong adhesion between the water molecules
• condensation
• water cycle

Weak attractive forces forming between oppositely charged regions of two different water molecules is called a(n)

• Covalent bond

• Ionic bond

• Polar bond

• Hydrogen bond

Water is polar because...

• The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
• The molecule has two poles, at which the it is colder than other regions of the molecule.
• The unequal sharing of electrons gives the water molecule a slight negative charge near its hydrogen atoms and a slight positive charge near its oxygen atom.
• The water molecule is neutral.

• Carbon

• Hydrogen

• Oxygen

• Sodium
