SUMMARY

The discussion centers on the relationship between entropy (S) as a function of energy (U) and its compliance with the second law of thermodynamics. Participants clarify that S as a function of U does not violate the second law, as entropy is inherently maximized in thermodynamic processes. The Sackur-Tetrode Equation is highlighted as a relevant tool for understanding this relationship in the context of monatomic ideal gases.

PREREQUISITES
  • Understanding of the second law of thermodynamics
  • Familiarity with entropy and its mathematical representation
  • Knowledge of the Sackur-Tetrode Equation
  • Basic concepts of thermodynamic systems and ideal gases
NEXT STEPS
  • Study the Sackur-Tetrode Equation in detail
  • Explore the implications of the second law of thermodynamics on various thermodynamic processes
  • Investigate different entropy functions and their compliance with thermodynamic laws
  • Learn about monatomic ideal gases and their properties in thermodynamics
USEFUL FOR

Students of thermodynamics, physicists, and anyone seeking to deepen their understanding of entropy and its role in thermodynamic laws.

if given enropy S as a function of energy U how do i tell that is obeys the second postulate?
 
Physics news on Phys.org
is there no one who can help?
 
i had the same question lol

I am not sure what you mean by the second postulate. Do you mean the second law of Thermodynamics? (it is not a postulate).

in our class there were 4 postulates. the second was that entropy is maximized. we were given a few entropy functions and had to decide which ones violated the second postulate
 
S given as a function of U doesn not violate the second law of thermodynamics..because S IS a function of U...
look up the Sackure-Tetrode Equation for a monatomic ideal gas
