From the given substances the substance with higher entropy should be identified. A sample of pure silicon or a piece of silicon containing trace of other element such as boron or phosphorus. Concept Introduction: Entropy is a measure of the randomness of the system. It is a thermodynamic quantity and an extensive property. It is represented by the symbol S . It can also be defined as the degree of energy dispersal. More the dispersal in energy, more is the value if entropy.

(a)

Interpretation Introduction

Interpretation:

From the given substances the substance with higher entropy should be identified.

A sample of pure silicon or a piece of silicon containing trace of other element such as boron or phosphorus.

Concept Introduction:

Entropy is a measure of the randomness of the system. It is a thermodynamic quantity and an extensive property. It is represented by the symbol S. It can also be defined as the degree of energy dispersal. More the dispersal in energy, more is the value if entropy.
