Water is essential for life on the planet. High specific heat capacity is an important property of water. Why is it particularly important to marine life--plants and animals living in bodies of water?

• Cohesive properties enable all forms of life to live in and on the water.

• Adhesive properties enable many forms of life to live in and on the water.

• Bodies of water never freeze totally, preserving marine life.

• Bodies of water never freeze totally due to water’s ability as a universal solvent, preserving marine life

Of the following, which is the best explanation to compare adhesion and cohesion?

• Adhesion is the attraction between molecules of different substances, and cohesion is the attraction between molecules of the same substance. Both attract only nonpolar substances.

• Adhesion is the attraction between molecules of the same substance, and cohesion is the attraction between molecules of different substances.

• Cohesion is the attraction between molecules of different substances, and adhesion is the attraction between molecules of the same substance.

• Adhesion is the attraction between molecules of different substances, and cohesion is the attraction between molecules of the same substance.

Why is water known as the universal solvent?

• It can dissolve more substances than any other liquid.

• It is found everywhere on Earth.

• It can dissolve gases and solids equally well.

• It is the most abundant liquid on Earth.

Review the image, above. One drop each of water (H₂0) and of ethyl alcohol (C₂H₅OH) were placed onto a glass slide, as illustrated. Which of the following is the best explanation for the difference in appearance of the two liquids?

• Water molecules have less universal solvent properties than ethyl alcohol molecules.

• Water molecules have more cohesion properties than ethyl alcohol molecules.

• Water molecules have less adhesion properties than ethyl alcohol molecules.

• There is weaker hydrogen bonding within the water molecule than within the molecule of ethyl alcohol.

Evaluate the impact of water's high specific heat capacity on coastal climates. How does this property of water affect marine ecosystems?

• It causes extreme temperature variations

• It leads to more frequent storms

• It moderates air and water temperature changes, leading to milder climates

• It decreases humidity levels in coastal areas
