Thermodynamics: Reversible Compression of Solid Volume V

Click For Summary
SUMMARY

The discussion focuses on the reversible compression of a solid volume V from pressure P1 to pressure P2 isothermally at temperature T within the context of thermodynamics. It establishes that during this reversible process, the internal energy of the solid can change, and emphasizes that the entropy remains constant, indicating no increase in entropy throughout the process. This highlights the significance of reversibility in thermodynamic processes, particularly in relation to energy and entropy changes.

PREREQUISITES
  • Understanding of thermodynamic principles, specifically the laws of thermodynamics.
  • Familiarity with concepts of pressure, volume, and temperature in relation to solids.
  • Knowledge of entropy and its implications in reversible processes.
  • Basic grasp of internal energy changes in materials during compression.
NEXT STEPS
  • Study the implications of the first and second laws of thermodynamics in solid-state processes.
  • Learn about the mathematical modeling of isothermal processes in solids.
  • Explore the concept of entropy in greater detail, particularly in reversible and irreversible processes.
  • Investigate real-world applications of reversible compression in engineering and materials science.
USEFUL FOR

Students and professionals in physics, engineering, and materials science who are interested in thermodynamic processes, particularly those involving solids and reversible transformations.

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!
