Question

match the property of water with its description.
a. waters ability to attract other water molecules
b. waters ability to absorb large amounts of thermal energy before its temperature increases
c. waters ability to float as a solid
d. waters ability to attract other polar substances
e. waters ability to dissolve substances
a. universal solvent
b. adhesion
c. high heat capacity
d. cohesion
e. density

Explanation:

• Cohesion (D): Cohesion is the attraction between like molecules. Since water molecules are polar, they are attracted to each other through hydrogen bonds. So, water's ability to attract other water molecules (a) is cohesion.
• High heat capacity (C): Heat capacity is the amount of heat energy required to raise the temperature of a substance. Water has a high heat capacity, meaning it can absorb a large amount of thermal energy before its temperature increases. Thus, water's ability to absorb large amounts of thermal energy before its temperature increases (b) is high heat capacity.
• Density (E): Density is mass per unit volume. Ice (solid water) is less dense than liquid water, which is why it floats. So, water's ability to float as a solid (c) is due to density.
• Adhesion (B): Adhesion is the attraction between unlike molecules. Water is polar and can form hydrogen bonds with other polar substances. Therefore, water's ability to attract other polar substances (d) is adhesion.
• Universal solvent (A): Water is called the universal solvent because it can dissolve many substances. So, water's ability to dissolve substances (e) is because it is a universal solvent.

Answer:

a. D. Cohesion
b. C. High heat capacity
c. E. Density
d. B. Adhesion
e. A. Universal solvent
