Question

question 4 of 20 : select the best answer for the question. 4. a unique property of water because of its chemical structure is that its ______ dense when its a solid than when its a liquid. a. inversely b. equally c. more d. less mark for review (will be highlighted on the review page)

Explanation:

Water's unique molecular structure (hydrogen bonding) causes ice (solid water) to have a more open, less dense structure than liquid water. So solid water is less dense than liquid water. Option A (inversely) is about a relationship, not density comparison here. Option B (equally) is wrong as densities differ. Option C (more) is opposite of the correct fact. Option D (less) matches the property.

Answer:

D. less
