SSC Chemistry notes 2nd Chapter 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 Chemistry notes 2nd Chapter the 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 a gaseous state.
teachingbd24.com is such a website where you will get all kinds of necessary information regarding educational notes, suggestions and question patterns of schools, colleges, and madrasas. 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 33 years as an Assistant Professor of Physics at BAF Shaheen College Dhaka. He expects that this website will meet up all the needs of Bengali version learners /students. He has requested concerned students and teachers to spread this website home and abroad.
