properties of matter ppt

It is a matter of common experience that the objects inside a dark room, which are invisible, become visible when the room is illuminated by a source of light. Thus light can be defined as the external cause responsible for the sensation of vision. The branch of Physics dealing with the n..

Importance of Chemistry - The branch of science, which deals with the study of matter, its composition, its properties and the changes that it undergoes in composition as well as in energy during various processes, is defined as chemistry. It has been further divided into differ..

We heat raw food to soften it. We freeze water into ice by cooling it in refrigerator. When we boil water in a kettle we observe the steam oozing from the mouth of the kettle. When the cork is difficult to remove, we slightly heat the mouth of the bottle, so that the cork comes out easily. Through ..

These are bacteria which are unable to manufacture their own organic food and hence are dependent on external source. These bacteria can be distinguished into three groups as follows: Saprophytic Bacteria: These bacteria obtain their nutritional requirements from dead organic matter. They..

A change in which the composition of a substance is altered is called as chemical change of matter. As a result, the original properties get changed and one or more new substances are formed. Iron is greyish white metal and conducts electricity. It is attracted by a magnet, and ..

Inertia can be defined as the property of matter by virtue of which it opposes any change in its state of rest or of uniform motion along a straight lin..

In 1819, two French physicists Dulong and Petit discovered that the average molar specific heat at constant pressure for all metals, except the very light ones, is approximately the same and equal to nearly 25 J mole -1 o C -1 . Although the law is an approximate one, it conveys a very important id..

Dulong and Petit Law (Specific Heat of Solids) - In 1819, two French physicists Dulong and Petit discovered that the average molar specific heat at constant pressure for all metals, except the very light ones, is approximately the same and equal to nearly 25 J mole -1 o C -1 . Although the law is a..
