Lewis made an important contribution in

Lewis made an important contribution in the field of theoretical physics, particularly to the study of chemical thermodynamics. He developed a theory of chemical attraction and valence with the American physical chemist Irving Langmuir, based on the atomic structure of substances, known as the Langmuir-Lewis theory ( "see "Atom). Lewis is also known for his work on the theory of solutions and the application of the principles of thermodynamics to chemical problems.
