A representation of liquid water is shown below. Which of the three representations that follow best describes the water after it has boiled into steam?

Chapter 12, Problem 2SC, A representation of liquid water is shown below. Which of the three representations that follow best

Interpretation Introduction

Interpretation:

The given representation that best describes water after boiling is to be determined.

Concept Introduction:

The boiling point of a molecule depends upon its intermolecular forces and thermal energy.

Intermolecular forces keep molecules together. Greater the intermolecular force, greater will be its boiling point.

Thermal energy is acquired by molecules in motion. Higher the temperature, greater will be the motion of the molecules or atoms.

Boiling a substance can change its thermal energy and intermolecular forces but not the chemical bonds present between its atoms.

Explanation of Solution

Reason for the correct option:

Boiling a substance can change its thermal energy and intermolecular forces but not the chemical bonds present between its atoms. So, when water is boiled, the intermolecular forces between its molecules decrease and the randomness or thermal energy of the molecules increases.

Hence, option (b) is correct...
