AP Biology Unit 1 Water Properties

Front

What type of bond is found BETWEEN water molecules?

Back

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

Front

What word describes when water is attracted to other substances?

Back

Adhesion is the property of water that allows it to be attracted to other substances, such as glass or plant tissues.

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, moderating the climate.

Front

What phenomenon occurs due to cohesive forces between water molecules and adhesive forces with other molecules?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, due to cohesion and adhesion.

Front

Why does water bead up on the surface of a penny?

Back

Water beads up on a penny due to high surface tension, which is a result of cohesive forces between water molecules.

Front

What is the term for the attraction between water molecules?

Back

Cohesion is the property of water that describes the attraction between water molecules, allowing them to stick together.

Front

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid, making it essential for life.

Front

What is surface tension?

Back

Surface tension is the elastic tendency of a fluid surface that makes it acquire the least surface area possible, allowing it to resist external force.

Front

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

Back

Water's high specific heat allows it to absorb and store large amounts of heat energy, helping to regulate temperature in the environment.

Front

What is the difference between cohesion and adhesion?

Back

Cohesion refers to the attraction between like molecules (water to water), while adhesion refers to the attraction between unlike molecules (water to other substances).
