But unlike ordinary gases( which are neutral), plasmas are made up of electrically charged particles(ions and electrons). Like gases, plasma have not fixed shape and volume, and are less dense than solids or liquids. The mixture of electrons and nuclei forms plasma state of matter. Eg.Īt very high temperature(of stars), atoms lose their electrons. On the other hand, on cooling – gas changes to liquid and liquid changes to solid. Generally, on heating – solid changes to liquid and liquid changes to gas. Differences between solid, liquid and gas : But, matter on earth exists mostly in three states: solid, liquid and gas. There are four states of matter in the universe: solid, liquid, gas and plasma. They all have mass and occupy space.Ĭlassification of matter can be done by two ways – physical and chemical classification. Matter and it’s classificationĪnything that occupies space and has weight and can be felt (by any one or more of our senses) is called matter.Įverything that is around us including the pen, book, pencil, air, all living beings are composed of matter. Chemistry is part of everything in our lives. Understanding basic chemistry concepts is important for almost every profession. Many people think of chemists as being white-coated scientists mixing strange liquids in a laboratory, but the truth is we are all chemists.
Chemistry is one of the physical sciences that help us to describe and explain our world. Chemistry is involved in everything we do, from growing and cooking food to cleaning our homes and bodies to launching a space shuttle. Every material in existence is made up of matter - even our own bodies. The branch of science which deals with the study of composition, structure, properties and change of matter is called chemistry.
