AP Biology Topic 1.1 Properties of Water

Front

What type of bond connects the hydrogen atoms to the oxygen atom in a water molecule?

Back

Polar covalent bonds.

Front

What effect does the high surface tension of water have?

Back

A water strider can walk across the surface of a small pond.

Front

What is the attraction between the slight negative charge of one water molecule and the slight positive charge of another called?

Back

A hydrogen bond.

Front

Why is water able to form hydrogen bonds?

Back

The bonds that hold together the atoms in a water molecule are polar covalent bonds.

Front

What property of water allows it to dissolve almost any substance?

Back

Universal Solvent.

Front

What is the unique density property of ice?

Back

Ice is less dense than liquid water, allowing it to float.

Front

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

Back

It helps regulate temperature in organisms and environments.

Front

What does it mean for water to be a polar molecule?

Back

It has a partial positive charge on one side and a partial negative charge on the other.

Front

How does water's cohesion contribute to its properties?

Back

It allows water molecules to stick together, leading to surface tension.

Front

What is adhesion in the context of water?

Back

The attraction between water molecules and other substances.
