Thermodynamics
What is Thermodynamics?
Thermodynamics is the branch of physical science that deals with the relationships between heat, work, temperature, and energy. Its four laws govern the direction and extent of chemical reactions and physical processes. Key functions include internal energy (U), enthalpy (H), entropy (S), and Gibbs free energy (G = H − TS). A reaction is spontaneous at constant T and P when ΔG < 0.
