First law of thermodynamics: The first law of thermodynamics uses

The first law of thermodynamics uses the principles of energy conservation. It establishes a relationship between the internal energy of a system, heat transfer, and work done. According to the first law , the change in internal energy equals the heat supplied to the system minus the work done by the system [1-4]. The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. It can, however, be transferred from one location to another and converted to and from other forms of energy. Main Idea The First Law of Thermodynamics is another way to state Conservation of Energy and The Energy Principle. Hence, if needed, review those topics before diving into The First Law of Thermodynamics . Heat, the transfer of thermal energy, and internal energy, the energy possessed by the constituents of the system, are forms of energy, just like Kinetic Energy and Potential Energy. We can now extend the scope of the Law of Conservation of Mechanical Energy from Work and external potential ... Learn the definition, equation and examples of the First Law of Thermodynamics , which deals with the conservation of energy in chemical and physical processes. Explore how heat, work and internal energy are related and how they change in different types of processes.
