Question

Which branch of chemistry would take the results of an experiment and determine what the results would be at different conditions?
A.Physical chemistry
B.Nuclear chemistry
C.Radiochemistry
D.Analytical chemistry

Answer 1

Hint: Chemistry is a branch of science which deals with the study of matter, substances, and the properties of substances. Basically, chemistry deals with the interaction of matter and energy. There are many branches of chemistry like Analytical Chemistry, Physical chemistry, Inorganic chemistry, Organic chemistry, Biochemistry, Nuclear chemistry, and Radiochemistry.

Complete step by step answer:
We have to find the branch of chemistry that would take the results of an experiment and determine what the results would be under different conditions. So first let us know about the branches of chemistry given in the option-
1.Physical chemistry- deals with the study of behavior of matter either at an atomic level or a molecular level.
In this branch, properties of substances are studied at different scales from macroscopic to subatomic level.
 In this branch we take the results of an experiment and determine what the results would be under different conditions.
2.Nuclear chemistry-In nuclear chemistry, we study the physical and chemical properties of an element influenced by changes in the structure of atomic nucleus. It basically deals with nuclear reactions and their uses.
3.Radiochemistry-is the study of radioactive particles. In this we study about the formation of radioactive particles, their properties, uses and proper disposal of radioactive wastes.
4.Analytical Chemistry-In this branch we deal with analysis of different substances. In this we separate the mixtures and identify the substances forming the mixture and their concentration in the mixture.

The correct answer is A.

Note:
If the students are confused about macroscopic scale and subatomic scale then they should know that-
-Macroscopic scale involves substances that are visible to the human eyes means it involves the substance’s physical state only. It does not deal with the molecule's chemistry. In this we measure-enthalpy, melting point and boiling point.
-Subatomic scale involves the study of such particles that are smaller in size than the atoms. In this level factors like temperature and pressure do not have any effect on the particle.
