Question

sugar dissolves in coffee because
multiple choice
water is less dense than ice.
water is a good solvent.
water has high heat capacity.
water is cohesive.
water is able to change from a gas to a solid.

Explanation:

• Option A: Water is denser than ice (ice floats on water), so this is incorrect.
• Option B: Coffee has water, and water's polarity makes it a good solvent, allowing sugar (a solute) to dissolve. This matches the dissolution process.
• Option C: High heat capacity relates to temperature regulation, not dissolution, so incorrect.
• Option D: Cohesion is about water molecules sticking to each other, not dissolving solutes, so incorrect.
• Option E: Water changes from gas (vapor) to liquid to solid (ice), not directly gas to solid (deposition is rare in this context and not related to dissolution), so incorrect.

Answer:

B. water is a good solvent.
