Concept explainers
Interpretation:
The major importance of studying chemistry needs to be explained.
Concept introduction:
Chemistry tells about the matter, energy and the interaction between molecules. Chemistry can be called as the "central science" because it connects other branches of sciences, such as biology, physics, etc. Study of chemistry gives information about the whole universe.
Explanation of Solution
Chemistry is not all about experiment observation and results. It explains the nature of chemicals or exposing materials as well as their physical states like liquid, gas, or solid. Different types of
Hence from these types of information, it can be concluded that with the help of chemistry all other branches of science can be understood.
