Properties of Water

Explain the property of water known as cohesion.

• Cohesion is the attraction between molecules of different substances, in this case, water molecules.

• Cohesion is the repulsion between molecules of the same substance, in this case, water molecules.

• Cohesion is the tendency of water molecules to separate and form bubbles.

• Cohesion is the attraction between molecules of the same substance, in this case, water molecules.

Describe the property of water known as adhesion and provide an example.

• An example of adhesion is water sticking to the inside of a glass or to the surface of a plant's leaves.

• Water freezing on the inside of a glass

• Water repelling from the inside of a glass

• Water evaporating from the surface of a plant's leaves

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

• Water's high specific heat capacity only affects non-living matter

• Water's high specific heat capacity has no significance in biological systems

• Water's high specific heat capacity is not related to temperature regulation

• Water's high specific heat capacity is significant because it helps to regulate temperature in living organisms and maintain stable environmental conditions.

Explain how water's ability to dissolve many substances makes it essential for life.

• Water's ability to dissolve many substances is essential for life because it allows for various biological processes to occur, such as nutrient transport, waste removal, and maintenance of a stable internal environment.

• Water's ability to dissolve many substances is not essential for life because it hinders the growth of plants and animals.

• Water's ability to dissolve many substances is not essential for life because it causes dehydration in living organisms.

• Water's ability to dissolve many substances is not essential for life because it leads to contamination of the environment.

How does water's surface tension contribute to its ability to support small objects?

• Surface tension creates a 'skin' on the surface of water, allowing it to support small objects.

• Surface tension creates a vacuum effect, pushing small objects away

• Surface tension makes water less dense, allowing small objects to sink

• Surface tension causes water to repel small objects

Explain the property of water that allows it to act as a solvent for polar and ionic substances.

• Water's pH level allows it to act as a solvent for polar and ionic substances.

• Water's density allows it to act as a solvent for polar and ionic substances.

• Water's polarity allows it to act as a solvent for polar and ionic substances.

• Water's temperature allows it to act as a solvent for polar and ionic substances.

Discuss the property of water that makes it an effective medium for transporting nutrients in living organisms.

• Water's high polarity and ability to form hydrogen bonds

• Water's low polarity and inability to form hydrogen bonds

• Water's tendency to repel other molecules

• Water's high acidity and lack of solubility

Explain the property of water that allows it to have a lower density as a solid than as a liquid.

• The property of water that allows it to have a lower density as a solid than as a liquid is because it contains more air bubbles when frozen.

• The property of water that allows it to have a lower density as a solid than as a liquid is due to its higher molecular weight when frozen.

• The property of water that allows it to have a lower density as a solid than as a liquid is because it contracts when it freezes.

• The property of water that allows it to have a lower density as a solid than as a liquid is due to its unique crystalline structure when frozen.

Describe the property of water that allows it to have a high heat of vaporization and its importance for living organisms.

• Water's high heat of vaporization is a result of its low specific heat, which is not significant for living organisms.

• Water's high heat of vaporization is due to its low boiling point, which is not important for living organisms.

• Water's hydrogen bonding leads to a high heat of vaporization, which is important for efficient cooling in living organisms.

• Water's high heat of vaporization is caused by its lack of hydrogen bonding, which is not relevant for living organisms.
