Chapter 4, Problem 4F.1E

(a)

Interpretation Introduction

Interpretation:

The rate at which heat generate entropy in the surrounding has to be determined.

Concept Introduction:

The degree of randomness in a system is the measured in terms of entropy.  Higher the entropy greater will be the disorder in the system.   The mathematical expression for the calculation of entropy of the system is shown below.

$\Delta \text{S}=\frac{{\text{q}}_{rev}}{\text{T}}$

(b)

Interpretation Introduction

Interpretation:

The entropy generate per day in the surrounding has to be determined.

Concept Introduction:

Same as part (a).

(c)

Interpretation Introduction

Interpretation:

The entropy generated is greater or less at $30°C$ has to be predicted.

Concept Introduction:

Same as part (a).
