Chapter 6, Problem 1RQ

Interpretation Introduction

Interpretation:

Similarity and dissimilarity between solid and liquid should be identified.

Concept introduction:

The liquid can be compressed and have loosely packed molecules so that it cannot retain a shape in comparison to solid in which molecules are tightly packed to give it a specific shape. Hence, solid and liquid have some similarities and dissimilarities as well.

Answer to Problem 1RQ

Solution:

Liquid and solid have fixed volume and can change their state when subjected to heat.

In solid the molecules are tightly packed whereas liquid having loosely packed molecules but both of them are present in the condensed phase.

Explanation of Solution

Liquid and solid have fixed volume and can change their state when subjected to heat.

Solid and liquid are present in the condensed phase or their molecules are closer in comparison to gaseous in which molecules are far apart.

In solid, the molecules are tightly packed with each other. The molecules in solid are so closely packed so that their movement is so reduced to give it a confined structure of solidity whereas liquid having loosely packed molecules which cannot give it a perfect shape.

The molecules of solid and liquid can be represented as follows:

  Solid    Liquid

Conclusion

Hence, in solid the molecules are tightly packed whereas liquid having loosely packed molecules but both of them are present in the condensed phase.
