Chapter 19, Problem 1E
Interpretation Introduction

Interpretation:

Spreading out of energy should be explained.

Concept introduction:

As per the law of conservation of energy rate:

• The energy can neither be created nor be destroyed.

• The energy can be transmitted from one form to another.

As per second law of thermodynamics:

• Energy always transfers from higher concentration reason to lower concentration reason which never reverses.

Given:

The energy spreads out.
