Homework Help Overview

The discussion revolves around a thermodynamics problem involving two subsystems characterized by their pressure, volume, and temperature. The original poster seeks to find a relationship between these thermodynamic coordinates when the subsystems reach equilibrium, particularly focusing on the conditions of equal temperature and pressure.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to establish a relationship between the specific volumes of the subsystems at equilibrium, questioning if the equality of pressures and temperatures leads to a specific volume relationship. Other participants raise questions about the mass or number of moles in each subsystem, indicating a consideration of additional factors in the equilibrium state.

Discussion Status

The discussion is ongoing, with participants exploring various aspects of the problem. Some guidance has been provided regarding the need to consider mass or moles, but there is no explicit consensus on the approach or solution. The original poster expresses uncertainty about missing subtle points in their reasoning.

Contextual Notes

Participants have noted the lack of additional conditions provided in the problem statement, which may affect the analysis. There are also requests for broader resources and equations related to thermodynamics, indicating a need for foundational knowledge in the subject.

Homework Statement



Two subsystems with thermodynamic parameters (P1,V1,T1) and (P2,V2,T2) are separated by a movable diathermal wall Find the relation if any between the thermodynamic co-ordinates when they attain equilibrium.

Homework Equations


The Attempt at a Solution



What I understand is at the thermodynamic equilibrium point the temperature of the system (and hence for both the subsystems) will be the same,T'1=T'2= T.The piston will mobe a bit and the two pressures P'1 and P'2 will be equal to each other as well.The volumes will be changed...

But are there any more subtle point that I am missing?There are no more conditions given...
Should it be anything like this:

(P'1*v'1/T)=(P'2*v'2/T) and hence, v'1=v'2?

where v'1 and v'2 are the specific volumes...
 
Physics news on Phys.org
What about the mass or number of moles on either sides? Are they same?
 
could you please upload everythings about thermodynamic...please i need it
 
The answer is fully detailed in Callen, Thermodynamics and an Introduction to Thermostatistics. Please, borrow this famous book in your favorite library...
 
can you help me?? what is the equation for specific heat capacity? is it Y=Cp/Cv??

also i can't remember how to rearange the equation P1V1/T1=P2V2/T2 i need to get T2 on its own

please help I am really stuck
