Homework Help Overview
The discussion revolves around the thermodynamic properties of gases, specifically focusing on the relationship between heat capacities for ideal and Van der Waals gases. The original poster is tasked with demonstrating a relationship for an ideal gas and then deducing a similar relationship for a Van der Waals gas.
Discussion Character
- Exploratory, Conceptual clarification, Mathematical reasoning
Approaches and Questions Raised
- The original poster describes their approach to part a) using the ideal gas equation and partial derivatives to arrive at the relationship Cpm - Cvm = R. They express uncertainty about how to approach part b) regarding the Van der Waals gas.
- Some participants suggest evaluating the partial derivatives in the context of the Van der Waals equation and consider the implications of the triple product rule.
- There is a question about whether the same method used for the ideal gas can be applied to the Van der Waals gas.
Discussion Status
The discussion is ongoing, with participants exploring different methods and interpretations. Some guidance has been provided regarding the evaluation of partial derivatives and the application of the Van der Waals equation, but no consensus or resolution has been reached yet.
Contextual Notes
The original poster has successfully completed part a) but is struggling with part b). There is an emphasis on including all parameters except for pressure in the final answer for part b), which may complicate the approach.
