Definition of physical chemistry Physical chemistry stands in the same relation to the subdivisions of chemistry in which philosophy stands toward all the sciences. Its main object is to unify thought within the science of chemistry; therefore, it might well be named, the "philosophy of chemistry'-SLBigelow, 1912
