Physics is related to chemistry, in a way that physics is also concerned about how atoms and molecules react, or in other words, move, when subjected to pressure and another chemical. The fizzing, bubbling, and smoking of substances, we can apply the laws of physics to these. Physics can be associated practically with everything.
1 Physical chemistry has a large overlap with theoretical chemistry and molecular physics. 2  Physical chemistry involves the use of calculus in deriving equations. 3  Theoretical chemistry is the study of chemistry via theoretical reasoning (usually within mathematics or physics).
