Question

sugar dissolving in coffee (which contains water)... universal solvent specific heat cohesion adhesion

Explanation:

To determine the correct option, we analyze each term:

• Universal solvent: Water is known as the universal solvent because it can dissolve many substances, including sugar. When sugar dissolves in coffee (which has water), this property of water (acting as a universal solvent) is demonstrated.
• Specific heat: Refers to the amount of heat required to raise the temperature of a substance, not related to dissolving.
• Cohesion: Is the attraction between molecules of the same substance (e.g., water molecules sticking to each other), not about dissolving.
• Adhesion: Is the attraction between molecules of different substances (e.g., water sticking to a glass), not about dissolving.

So the property related to sugar dissolving in coffee (with water) is the universal solvent property of water.

Answer:

A. universal solvent
