classification of matter according to organ

The indivisibility of an atom was proved wrong, for, an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle, which takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects. T..

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..

The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles, then it should be possible for matt..

According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystalline. A solid is a crystalline substance in which the mol..

Properties of Matter - A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually ..

Introduction - 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..

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 In Our Surroundings One of the most famous formulas in the world is E = mC 2 , where E is energy, m is mass and C is the speed of light Everything in the world can be organized around two concepts matter and energy . If something isn't ..

Each and every living organism has its specific surrounding medium of environment with which it continuously interacts and remains fully adapted. The environment is the sum total of physical and biotic conditions influencing the responses of the organisms. The life supporting en..
