Thermodynamics: Reversible Compression of Solid Volume V

AI Thread Summary
In thermodynamics, a block of volume V is reversibly compressed isothermally from pressure P1 to P2 at temperature T. The internal energy of a solid can change during this process, even though it is not an ideal gas. The concept of reversibility implies that the entropy of the process does not increase, indicating that the process can be reversed without any net change in the system and surroundings. This characteristic allows for the deduction of specific thermodynamic properties related to efficiency and energy transfer. Understanding these principles is crucial for analyzing thermodynamic systems effectively.

Hi, this concerns thermodymanics.

A block of volume V is reversibly compressed from pressure P1 to pressure P2 isothermally at temperature T.

It goes on to ask about the heat expelled, but that's not my question.

It is a solid, obviously not an ideal gas, so I'm sure the internal energy can change, yes?
Also, what information can we deduce from the fact that it's a reversible process, if any?

Thanks.

When a process is said to be 'reversible' (thermodynamically), then you're saying something very specific about the entropy of the process.
 
Ah ha! The entropy doesn't increase, I see. Thanks!

Thread 'Gauss' law seems to imply instantaneous electric field propagation'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
