Chapter 2, Problem 2.32NP

Interpretation Introduction

Interpretation: The number of moles of ideal gas is 2.35 mol at 415 K. The initial and final pressure is 18.0 bar and 1.75 bar respectively. The process resulting in the maximum work done by system and the value of work done need to be determined. Also, the process resulting in the minimum work done by the system and the value of work needs to be determined. The least amount of work done needs to be determined without restrictions on the $P_{\text{external}}$ .

Concept Introduction: The work done can be calculated as follows:

  $w=-P_{\text{external}}\left(V_f-V_i\right)$

Here, P is external pressure, $V_f$ and $V_i$ is final and initial volume respectively.
