Chapter 18, Problem 18.37QP

Interpretation Introduction

Interpretation:

The given nursery rhyme in terms of second law of thermodynamics has to be explained.

Concept Information:

First law of thermodynamics: According to first law, the total energy of the universe remains constant.

Second law of thermodynamics:  According to second law of thermodynamics, the entropy of the universe is the sum of the entropy of the system and the surroundings.  For all spontaneous process the entropy of the universe increases.

1. 1. The second law of thermodynamics gives more information about the thermodynamic process.
2. 2. Second law may be defined as “ Heat cannot flow itself from colder body to a hotter body”
3. 3. The second law is also used to determine the theoretical limit for the performance of mostly used engineering systems like heat engines and heat pump.
