Identify the branches of Chemistry in the following cases.
Difficulty: Medium
| Scenario | Branch of Chemistry |
| Hair contain a special class of proteins called keratin which are present in nails and wool. | Biochemistry, since protein occurs in living organism. |
| Acetylene is the simplest hydrocarbon that contains carbon-carbon triple Bond. Hydrocarbons are the compounds of carbon and hydrogen. | Organic chemistry, since it deals with properties of organic compounds. |
| White lead is a pigment used by artists for centuries, the metal Pb in the compound is extracted from its ore, galena (PbS). | Industrial chemistry, since large scale production of any substance is the subject of industrial chemistry. |
| Sulphuric acid is a weaker than Hydrochloric acid. | Analytical chemistry, since it deals with analysis of a compound. |
| Gases can be compressed by applying pressure. | Physical chemistry, explanation of its transformation into gaseous state or solid state, applications of laws and theories to understand its structure is physical chemistry. |
| Some examples of complete protein food are meat, milk and eggs. | Biochemistry, since protein occurs in living organism. |
| Element radium decays by emitting -particles and is converted into another element radon. | Nuclear chemistry, since nuclear change can convert an element into another element. |
| Calorimeter is a device that measures the amount of heat, a substance absorbs on eating or emit on cooling. | Analytical chemistry the method and instruments used to determine its percentage composition melting point, boiling point etc. is analytical chemistry |
