Physical chemistry is the study of chemical systems at the molecular and macroscopic level using the methods of physics. It forms a bridge between chemistry and other disciplines such as materials science, chemical engineering, biochemistry, and physics. Physical Chemistry at UW-Madison encompasses a wide swath of topics that share a ... Physical chemistry deals with the principles of physics involved in chemical interactions. It examines: How matter behaves on a molecular and atomic level. How chemical reactions occur. Physical chemists are focused on understanding the physical properties of atoms and molecules, the way chemical reactions work, and what these properties reveal.

If \(P_{ext} = P_{int}\), the system is at equilibrium; the piston does not move, and no work is done. If the external pressure on the piston (P ext) is less than P int, however, then the ideal gas inside the piston will expand, forcing the piston to perform work on its surroundings; that is, the final volume (V f) will be greater than \(V_i ...
