Mechanism of chemical reactions through non kinetic methods can be done through many ways:
1. Product Identification
2. Evidence for an Intermediate
i) Isolation and characteristics of Intermediates
ii) Spectroscopic Identification of Intermediat
iii) Trapping the Intermediates
iv) Addition of Suspected Intermediate.
3. Isotopic Studies
4. Stereochemical Studies
5. Substituent Effect- Hammett Equation

There are four physical methods of resolving a mixture into its components: distillation, filtration, chromatography and crystallization. With these processes, there is no chemical reaction involved.
Heat (or thermal) energy is kinetic energy due to motion of atoms and molecules. It is energy that is in the process of being transferred from one object to another because of their temperature difference
Cancer is the result of natural phenomenon. The purpose of science is to explain natural phenomenon. Therefore, science is used to explain cancer. Medical care is considered a scientific field. Every doctor you have ever known has undergone extensive training in scientific knowledge and methods. Doctors who treat cancer, oncologists, are scientists too.
