Question

question 15
why does ice stay at the top of oceans instead of sinking to the bottom?
ice is more dense than liquid water
ice is colder than liquid water
ice is warmer than liquid water
ice is less dense than liquid water
large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. what is the reason for this phenomenon?
water acts as a buffer
water has a high heat capacity
water is a universal solvent
water is an acid

Explanation:

For the first question, substances with lower density float on those with higher density. Ice has a lower density than liquid water due to its open - lattice structure formed by hydrogen bonds. For the second question, water has a high heat capacity, which means it can absorb or release a large amount of heat energy without a significant change in temperature.

Answer:

Question 15: A. Ice is less dense than liquid water
Second question: Water has a high heat capacity
