Study Notes
Thermodynamics: Exploring the Foundations of Physics
Thermodynamics is a branch of physics that investigates the relationships between heat, work, energy, and entropy. It encompasses fundamental principles that govern the behavior of systems and their interactions with the environment. In this article, we'll delve into the subtopics of thermodynamics, highlighting the ongoing research and career opportunities in this field.
Key Concepts
- Heat: The transfer of energy from a high-temperature body to a lower-temperature body.
- Work: The expenditure of energy to perform mechanical tasks.
- Energy: The ability to do work.
- Entropy: A measure of the disorder or randomness of a system, often associated with the tendency for systems to evolve towards a more disordered state.
- First Law of Thermodynamics: States that energy can neither be created nor destroyed but can be transformed from one form to another or transferred from one system to another.
- Second Law of Thermodynamics: Postulates that the total entropy of an isolated system can never decrease over time, but it may remain constant or increase, and the increase in entropy is always associated with irreversible processes.
