Hydrogen and oxygen.

Front

Attractions between water molecules are called?

Back

Hydrogen bonds.

Front

Water beads up on the surface of a penny because of this property.

Back

High Surface Tension.

Front

Describe COHESION.

Back

Water molecules attracted to other water molecules.

Front

What is adhesion?

Back

Water's ability to stick to other substances.

Front

What is surface tension?

Back

The cohesive force between liquid molecules at the surface.

Front

What is the difference between adhesion and cohesion?

Back

Adhesion is attraction to other substances; cohesion is attraction to itself.

Front

What role do hydrogen bonds play in water's properties?

Back

They contribute to water's high surface tension and cohesion.

Front

How does temperature affect surface tension?

Back

Higher temperatures decrease surface tension.

Front

What is a polar molecule?

Back

A molecule with a partial positive charge on one side and a partial negative charge on the other.
