AP Biology Unit 1 Water Properties

Front

What property of water allows large bodies of water to moderate nearby climates?

Back

Water absorbs heat in the summer and slowly releases that heat in the winter.

Front

What is the term for the attraction between water molecules?

Back

Cohesion.

Front

What causes water to bead up on surfaces like a penny?

Back

High surface tension.

Front

Which part of a water molecule has a slightly positive charge?

Back

The hydrogen end.

Front

What is the reason water molecules stick together?

Back

One side has a positive charge and the other side has a negative charge.

Front

What is the term for the property of water that allows it to dissolve many substances?

Back

Water is a universal solvent.

Front

How does water's high specific heat benefit living organisms?

Back

It helps to stabilize temperatures in organisms and environments.

Front

What is the significance of water's polarity?

Back

It allows water to form hydrogen bonds, which are crucial for many biological processes.

Front

What is surface tension and how is it related to water?

Back

Surface tension is the cohesive force at the surface of water that allows it to resist external force.

Front

What is the difference between adhesion and cohesion in water?

Back

Cohesion is the attraction between water molecules, while adhesion is the attraction between water molecules and other substances.
