Question

23. STUDY OF MATTER AND ENERGY AND
INTERSECTION BETWEEN THEM-----

​

Answer 1

Answer:

Chemistry is the study of matter and energy at the scale of atoms and molecules.

Answer 2

""spectroscopy ""

Explanation :

As we know that "physics" is the study of matter and energy and also "spectroscopy" is also the interaction between matter and energy the what is the difference between these both terms?

Spectroscopy is one of many areas of physics that study the interaction of matter and energy, in fact all areas of physics deal with these interactions, from nuclear physics, to superconduction, to thermodynamics, and quantum theory, and many others. It is the basic essence of physics to study these phenomena. Spectroscopy is specifically the study of the electromagnetic energy released by those physical and chemical reactions which produce a distinct array of energy values in the form of a spectrum of values. The traditional spectrum analysis is of light emitted by combustion of elements, and is used both to identify the elements, and to determine the spacing of their electron orbitals. This is called atomic emission spectography. There is also the field of nuclear emission spectography which analyses the emission of gamma rays from radioactive sustances.
