SSC MCQ Question Ans. States of Matter

SSC MCQ Question Ans. The states of Matter. The matter is such a physical entity that has mass and occupies space. Usually, all matters can exist in three different states- solid, liquid and gaseous states. However, at normal room temperature, some matters can exist as solids, some as liquids and some as gaseous. The state of a matter is changed with the change of temperature. They have their own characters and properties in all three states but no changes take place in their molecular structure. The molecules in the solid state keep vibrating constantly staying very close to one another. These molecules get motion as they are heated and start moving away from one another. The solid, liquid and gaseous matters have the tendency of spreading in different media which may occur spontaneously or due to pressure.

SSC MCQ Question Ans. States of Matter

Every matter is made of small particles and can exist in any particular state- solid, liquid and gaseous states. The particles of a matter remain kinetic in each state. The arrangements of particles of a matter in three states are shown below. Draw the diagrams in your notebook and arrange them according to which is in the solid state, which is in the liquid state and which is in the gaseous state.

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.

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.

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.
