physicochemistry

Physicochemistry is the branch of science that studies how physical and chemical properties of substances interact and influence each other. It explores how materials behave—such as how they dissolve, change state, conduct heat or electricity, and react with other substances—by examining the underlying physical principles like energy, temperature, and molecular structure. This field helps us understand processes in nature and industry, from how medicines dissolve in the body to how materials are designed for specific functions. Overall, it bridges physics and chemistry to explain the behavior of matter at a molecular and macroscopic level.
