Chapter 15, Problem 35A

Interpretation Introduction

Interpretation: To state the consequences if the ice was denser than water.

Concept Introduction: Water can exist in all three forms of matter, i.e., solid, liquid, and gas. In solids, it exists in the form of ice. In gas, it exists in the form of water vapor or steam. In liquid, it exists in the form of liquid water.

Answer to Problem 35A

When ice becomes denser than water, it would sink into its own liquid.

Explanation of Solution

On cooling a liquid, the density of the liquid increases gradually due to the movement of liquid molecules as they come to each other. If the process of cooling continues, the liquid solidifies into a solid, thereby having a greater density than the density of a liquid.

Due to this reason, the solid sinks into its liquid as the density of the solid is greater than that of the liquid.

Conclusion

Thus, when ice becomes denser than water, it would sink into its liquid.
