What Is the Temperature of Each Block Before They Are Brought into Contact?

AI Thread Summary
The discussion focuses on determining the temperatures of two blocks modeled as Einstein oscillators before and after they come into contact. The first block has oscillators of frequency omega and energy E1, while the second block has oscillators of frequency 2omega and energy E2. The user seeks guidance on calculating the changes in entropy (dS) and energy (dE) to find the initial temperatures and the common temperature at thermal equilibrium. The relevant relationship between temperature, entropy, and energy is highlighted, emphasizing the need for further clarification on the calculations involved. The inquiry reflects a deeper exploration of thermodynamic principles in statistical mechanics.

I'm kind of stuck on this problem, if someone could help me out that would be appreciated.

Consider 2 blocks treated as collections of Einstein oscillators. The first block has N1 oscillators of frequency omega. The second block has N2 oscillators of frequency 2omega. Initially the first block has a total energy E1 and the second has a total energy E2. Both N1 and N2 are very large, of order Avagadro's number. E1/(ℏ omega ) and E2/(ℏ omega ) are also very large. The blocks are brought into contact and reach thermal equilibrium without any energy escaping to the environment.
  • What is the temperature of each block before they are brought into contact?
  • What is the common temperature after they reach thermal equilibrium?

Thank you.

For einstein solid,

1/T = dS/dE

Where E is internal energy and S is entropy. I can find relevant equations for E and S. But how do I calculate dS and dE?
Still not sure how to find their temp when in contact at equilibrium.
 
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...
