electrical in classification of matter

A conductor having excess electrons is said to be at a negative or at a lower potential and that having less electrons is said to be at a positive or at a higher potentia..

All around us are substances that are made of matter. Matter has mass and occupies some space. Different kinds of substances are made up of different matter. Matter can be thus classified in many ways. Two basic classifications of matter a..

Matter can be classified into different categories depending upon their physical or chemical natur..

The classification of matter into three different states, namely solid, liquid and gaseous state is termed as the physical classification of matter. Most properties of solid, liquid and gases that can be observed with our sense organs are called as 'mac..

All matter consists of atoms and molecules. Each of these atoms and molecules has certain amount of energy. The level of this energy decides the state in which the matter exists. When heat energy is supplied to matter, this energy level rises. As a result of this, sta..

Expansion of Matter - Matter expands on heating, i.e., solids, liquids and gases expand on heating. Let us consider expansion of solids: Three types of expansions are considered in case of solids. This classification is done according to the shape of the solid..

Is Matter Around us Pure Matter can be broadly divided into two major groups, 'Pure' and 'Impure'. In chemistry, the term 'purity' acquires quite a different meaning from what we understand it to be in our day-to-day life. Normally, when we refer to pure water, pure milk, et..

Matter and Materials - Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects that are solids. We say..
