SSC MCQ Question Ans. Chemistry and Energy

SSC MCQ Question Ans. Chemistry and Energy. In fact, a chemical bond is a store of energy. Energy is associated with the formation and breaking of chemical bonds. As the number of changing in chemical bond happened in the world, in all cases transformation of energy happened. We perform us every day works using the energy of the changes which occur spontaneously. The amount of this energy is finite in the world and is decreasing day the by day. So it is necessary to think about the alternative source of energy. In the meantime, the attempt is gone on to increase the number of lighting, making solar panels, using the power of the sun. On the other hand, an effort has been started to make use of nuclear power in our country like developed countries.

SSC MCQ Question Ans. Chemistry and Energy

We have known that elements in a molecule joined together by mutual energy between them. The energy by which the elements are joined together is chemical bonds. Besides these molecules or ions of a compound comes closer by energy named intermolecular force composed of various energy and create a particular state as solid, liquid and gaseous. The intermolecular force of ions or molecules of any solute, if high forms solid, if low forms liquid and if lower forms gaseous states. That is intermolecular force differs at different states of the same compound.

The word chemistry comes from the word alchemy, an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism, and medicine; it is commonly thought of as the quest to turn lead or another common starting material into gold.

Chemistry is a branch of science that involves the study of the composition, structure, and properties of matter. Often known as the central science, it is a creative discipline chiefly concerned with atomic and molecular structure and its change, for instance through chemical reactions.

Molecular geometry, also known as the molecular structure, is the three-dimensional structure or arrangement of atoms in a molecule. Understanding the molecular structure of a compound can help determine the polarity, reactivity, phase of matter, color, magnetism, as well as the biological activity.

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules, and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

The days are long past when one person could hope to have detailed knowledge of all areas of chemistry. Those pursuing their interests into specific areas of chemistry communicate with others who share the same interests. Over time a group of chemists with specialized research interests becomes the founding members of an area of specialization.

The areas of specialization that emerged early in the history of chemistry, such as organic, inorganic, physical, analytical, and industrial chemistry, along with biochemistry, remain of greatest general interest. There has been, however, much growth in the areas of polymer, environmental, and medicinal chemistry during the 20th century. Moreover, new specialties continue to appear, as, for example, pesticide, forensic, and computational chemistry.

This course provides students with the opportunity to develop their knowledge, understanding, and skills in relation to properties and structures of matter and a variety of chemical reactions incorporating organic compounds and acid/base equilibrium reactions.

Chemistry is one of the diverse branches of physical science. It is known as the science of life. The practice of chemistry has been in a constant increase since the ancient time. The present-day chemical industries have been evolved from the early practices of the Alchemists. Chemistry as a discipline encompasses a wide range of areas. It has always been devoted to the welfare of human and its environment. 

teachingbd24.com is such a website where you would get all kinds of necessary information regarding educational notes, suggestions and questions’ patterns of school, college, and madrasahs. Particularly you will get here special notes of physics that will be immensely useful to both students and teachers. The builder of the website is Mr. Md. Shah Jamal Who has been serving for 30 years as an Asst. Professor of BAF Shaheen College. He expects that this website will meet up all the needs of Bengali version learners /students. He has requested concerned both students and teachers to spread this website home and abroad.
