Overview of Thermodynamics
Thermodynamics is the branch of physics that deals with the relationships between heat, work, temperature, and energy. It provides a framework for understanding how energy is transferred and transformed in physical systems.
Key Concepts in Thermodynamics
1. Energy: The capacity to do work or produce heat. Energy can exist in various forms, such as kinetic, potential, thermal, and chemical.
2. Work: Defined as the energy transfer that occurs when a force is applied to an object and the object moves.
3. Heat: A form of energy that is transferred between systems or objects due to a temperature difference.
4. System and Surroundings: In thermodynamics, a system refers to the part of the universe under study, while the surroundings are everything outside the system.
