Water Properties

Front

What type of bond is found BETWEEN two water molecules?

Back

Hydrogen bonds are the attractions between the positive hydrogen atom of one water molecule and the negative oxygen atom of another.

Front

How do large bodies of water affect nearby climates?

Back

Large bodies of water absorb heat in the summer and slowly release that heat in the winter, helping to moderate nearby climates.

Front

What is cohesion in the context of water molecules?

Back

Cohesion is the attraction between water molecules themselves, not between water and different molecules.

Front

Why do water molecules stick together?

Back

Water molecules stick together because one side has a positive charge (hydrogen) and the other side has a negative charge (oxygen), creating polar attractions.

Front

Where are protons and neutrons found in an atom?

Back

Protons and neutrons are found in the nucleus of an atom.

Front

What is the definition of adhesion?

Back

Adhesion is the attraction between water molecules and different substances.

Front

What property of water allows it to have a high specific heat?

Back

Water's high specific heat is due to hydrogen bonding, which requires more energy to change its temperature.

Front

What is surface tension in water?

Back

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

Front

What is the significance of water being a polar molecule?

Back

Water's polarity allows it to dissolve many substances, making it an excellent solvent.

Front

How does water's density change when it freezes?

Back

Water expands and becomes less dense when it freezes, which is why ice floats on liquid water.
