Ch. 2 Properties of Water

Front

What do the green bonds represent?

Back

Hydrogen Bond

Front

Why does ice float?

Back

As water freezes, it expands and its density decreases.

Front

Attractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule are called?

Back

Hydrogen bonds

Front

What is cohesion?

Back

The ability of a molecule to 'stick' to itself.

Front

What property of water allows for water to act as a temperature regulator for the world?

Back

High Specific Heat.

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 adhesion?

Back

The ability of a molecule to 'stick' to other molecules.

Front

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

Back

It allows water to absorb and release large amounts of heat with little temperature change.

Front

What is surface tension?

Back

The cohesive force between liquid molecules at the surface of a liquid.

Front

What is the density of ice compared to liquid water?

Back

Ice is less dense than liquid water, which is why it floats.
