Which will have a higher temperature?

AI Thread Summary
In a discussion about the temperature comparison between wood and copper when heated to a steady state, it was established that both materials have the same dimensions and initial temperatures. The analysis focused on one-dimensional heat transfer under steady-state conditions. The application of Fourier's law of thermal flux and the general energy equation (GEE) indicated that the average temperatures at specific points for both materials were equal. This suggests that under the given conditions, neither material reaches a higher average temperature. The findings highlight the importance of material properties and heat transfer principles in thermal analysis.

Wood and Copper are heated upto a steady state condition which will have a higher average of temperature at points ?
Please state your mathematical approach
1. Homework Statement
Dimensions remain same for both the materials as well as the temperatures both are heated to is the same

Homework Equations


This is one dimensional heat transfer mainly with a steady state condition

The Attempt at a Solution


I have tried using Thermal Flux Fourier law as well as the normal GEE but both turned out same
 
Physics news on Phys.org
Turned out same as in the average of the temperature at points was equal

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
