Overview of Molecular Thermodynamics
Molecular thermodynamics is a branch of physical chemistry that focuses on the relationships between molecular properties and macroscopic thermodynamic behavior. It bridges the gap between quantum mechanics and classical thermodynamics, enabling a deeper understanding of how molecular interactions influence thermodynamic quantities such as energy, entropy, and temperature.
