Thermodynamics: Fundamentals Of Thermal-fluid Sciences 6th Edition
First and Second Laws of Thermodynamics
The first law of thermodynamics establishes the principle of energy conservation, stating that energy cannot be created or destroyed, only transferred or transformed.
The second law of thermodynamics introduces the concept of entropy, a measure of disorder or randomness. It dictates that the entropy of an isolated system can never decrease over time.
Entropy and Thermodynamic Processes
Entropy plays a crucial role in understanding thermodynamic processes. Irreversible processes, such as heat transfer through a temperature gradient, result in an increase in entropy.
Examples of thermodynamic cycles include:
