Chapter 4.7, Problem 4.13CE

Interpretation Introduction

Interpretation:

Does the given condition violates the first law of thermodynamics has to be explained.

Concept introduction:

The equation for the first law of thermodynamics can be given as,

  $\text{ΔU = q + w}$

• If system gains heat, then $\text{q}$= positive.
• If work is done on the system, then $\text{w}$= positive.
• If system loses heat, then $\text{q}$= negative.
• If work is done by the system, then $\text{w}$= negative.
