Physical chemistry is the study of macroscopic, atomic, subatomic, and particulate phenomena in chemical systems in terms of physical laws and concepts; often using the principles, practices and concepts of physics like motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics and dynamics.

Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a macroscopic or supra-molecular science, as the majority of the principles on which physical chemistry was founded are concepts related to the bulk rather than on molecular/atomic structure alone; for example, chemical equilibrium, colloids, etc.

Some of the relationships that physical chemistry has lately tried to resolve include the effects of:

1. Intermolecular forces on the physical properties of materials (plasticity, tensile strength, surface tension in liquids).
2. Reaction kinetics on the rate of a reaction.
3. The identity of ions on the electrical conductivity of materials.
4. Surface chemistry and electrochemistry of membranes.
