the branch of physical science that deals with the relationships between heat, work, and energy, particularly the principles governing the conversion of various forms of energy
- The first law of thermodynamics, also known as the law of conservation of energy, states that energy cannot be created or destroyed, only transferred or converted from one form to another.
- Thermodynamics plays a crucial role in understanding and optimizing the efficiency of heat engines, such as car engines and power plants.
- The second law of thermodynamics introduces the concept of entropy, indicating that natural processes tend to increase disorder in a closed system.
- Engineers use thermodynamics to analyze and design refrigeration and air conditioning systems, controlling temperature and heat transfer.
- The study of thermodynamics is essential in chemical engineering to understand and optimize chemical processes involving energy changes.
