Homework Help Overview
The discussion revolves around an irreversible isothermal process, specifically focusing on the work done when the external pressure is not provided. Participants are exploring the implications of this lack of information on calculating work and heat absorbed.
Discussion Character
- Exploratory, Assumption checking, Problem interpretation
Approaches and Questions Raised
- Participants are attempting to calculate work using different expressions but are questioning the validity of their approaches due to the absence of external pressure. There is also confusion regarding how external pressures are determined in the context of an irreversible process.
Discussion Status
The discussion is ongoing, with participants sharing their attempts and questioning the assumptions related to external pressure. Some guidance has been offered regarding the sketching of a PV diagram, but there is no explicit consensus on how to proceed with the calculations.
Contextual Notes
There is a noted concern about the changing nature of external pressure in irreversible processes, which may affect the calculations. Additionally, the original poster's attempts to derive work from given values are met with skepticism regarding their correctness.
