Question
Chapter 12, Problem 34E
Interpretation Introduction
Interpretation:
The effect on aquatic life is to be explained, if ice were denser than water.
Concept introduction:
Less denser substances tend to float on the surface of the relatively more denser substances. In general, ice being less dense than water floats on water surface. This layer of ice encapsulates small pockets of air which insulate the liquid water in the water bodies, protecting the aquatic life from external environment.
