Variation of energy but constant entropy

Click For Summary
SUMMARY

The discussion centers on the relationship between thermal energy transfer and entropy within a system, specifically questioning whether a system can maintain constant entropy while receiving thermal energy (Q) without wasting it. The Carnot cycle is referenced as a foundational concept in thermodynamics that illustrates the principles of energy efficiency and entropy management. The consensus indicates that maintaining constant entropy while absorbing energy is not feasible without external work or a specific thermodynamic process.

PREREQUISITES
  • Understanding of thermodynamic principles, particularly the laws of thermodynamics
  • Familiarity with the Carnot cycle and its implications for energy efficiency
  • Knowledge of entropy and its role in thermodynamic systems
  • Basic grasp of thermal energy concepts and heat transfer mechanisms
NEXT STEPS
  • Study the Carnot cycle in detail to understand its implications for energy transfer and efficiency
  • Explore the concept of entropy in thermodynamics and its mathematical formulations
  • Investigate real-world applications of thermodynamic principles in engineering
  • Learn about other thermodynamic cycles, such as the Rankine and Brayton cycles
USEFUL FOR

Students and professionals in physics, engineering, and thermodynamics, particularly those interested in energy systems and efficiency optimization.

Hello;

If a system receives a thermal energy Q, can it keep its entropy constant (that is, with equal value before it receives the energy) without wasting the energy received?
