Water Review

Front

What property of water helps to moderate earth's temperature?

Back

Specific heat capacity

Front

How does water's temperature change?

Back

Slowly, by adding a lot of energy

Front

What type of bond holds the Oxygen and Hydrogen atoms together in a water molecule?

Back

Covalent bond

Front

What property of water allows it to be called the 'universal solvent'?

Back

Polarity and cohesion

Front

Why is water considered polar?

Back

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.

Front

What is the significance of water's high specific heat capacity?

Back

It allows water to absorb and release large amounts of heat without significantly changing temperature, moderating climate.

Front

What is cohesion in relation to water?

Back

Cohesion is the attraction between water molecules, which allows for surface tension.

Front

What is adhesion in relation to water?

Back

Adhesion is the attraction between water molecules and other substances, allowing water to climb up plant roots.

Front

What happens to water when it freezes?

Back

Water expands upon freezing, making ice less dense than liquid water.

Front

What is the role of water as a solvent?

Back

Water dissolves many substances due to its polarity, making it essential for biological processes.
