For a chemical change they analyze the new substances to prove there has been a change in the chemical composition. I am not sure about physical though.
Chemical and physical changes are part of methods applied in science.
Correct characterization of matter chemical properties is possible by experimental studies; but theoretical methods exist for the approximate calculation the values for some chemical and physical properties.

No, Compounds Cannot Be Separated by Physical methods like Magnetic Separation , Filtration etc... They Can Be Only Separated By Chemical Means
Sterilization is the complete removal of all microorganisms ( e.g: becteria, virsues,...etc) from the surface area of 'anything' While Disinfection is an in-complete removal of microorganisms from" inanimate or nonliving" objects. and has three distinctive levels. High level disinfection, intermediate level, and low level. Both sterilization and disinfection have chemical and physical methods. And since the question is about the methods of sterilization then there are: physical methods: Heating and radiation chemical methods: some chemicals like 'Etheline Dioxide', or by chemical evaporation.
Experimentally; by chemical or physical methods.
Using many methods of chemical and physical analysis.
There are several physical and chemical methods depending upon nature of reactants and products.
No, compounds cannot be separated by physical methods. Because of their chemical bonds, they can only be separated by chemical methods.
Chemical and physical changes are part of methods applied in science.
so simple u duffer u don't no it one and only formation of anew substance having different chem properties
Yes it can. Water, table salt, and sugar are all examples of compounds and can all be decomposed into simpler substances through physical means.^^ I believed that water and table salt would be a mixture, mixtures are the non-chemical means not compounds, with compounds there is a chemical change.
Elements are substances that cannot be broken down into any simpler substances. Hence they cannot be broken down by chemical methods. They may change in appearance if physical methods, but chemically, they still remain as the element.
Analytical chemistry is the study of methods used to determine the chemical composition of materials.
Correct characterization of matter chemical properties is possible by experimental studies; but theoretical methods exist for the approximate calculation the values for some chemical and physical properties.
This research is possible only by chemical analysis, physical methods of analysis, radiometry.
