solid becomes a gas

has no definite volume or shape is fluid is very compressible. It takes the volume and shape of the vessel in which it is kept. For example: Hydrogen and carbon dioxide All the three states of matter are inter-convertible. For example: water When water is cooled to 0 o C, it transforms i..

Adsorption of Gases on Solids - Adsorption of gases on solids depends on the following factors: i) Nature of the gas (adsorbate) ii) Nature of the solid (adsorbent) iii) Specific area of the solid iv) Pressure of the gas v) Temperature vi)..

States of Matter - 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, state or the fo..

In general, solid waste includes garbage, domestic refuse and discarded solid materials such as those from commercial, industrial and agricultural operations. They contain increasing amounts of paper, cardboards, plastics, glass, old construction material, packaging material an..

More than 80 elements in the periodic table are metals. Metals are solids at ordinary temperature and pressure, with the exception (of mercury and gallium). Metals have characteristic properties such as: High thermal and electrical conductivity. Luster and high reflectivity. Malleability ..

Introduction - Gas is one of the three states of matter - the other two being liquid and solid. A gas differs from a solid and a liquid in a number of ways. A gas fills entire space available to it and therefore it has no definite shape or volum..

Summary - Gases are different from solids and liquids. They have no definite shape or volume. When pressure is applied, a gas contracts and when pressure is released, the gas expands. Gases can move in all directions and completely diffuse with other gases to form a ho..

Matter occurs in four states: Solid, Liquid, Gas and Plas..
