commercial air barrier

On commercial scale, nitrogen is obtained by the fractional distillation of liquefied air. The compressed carbon dioxide free air is liquefied by allowing it to expand in a region of low pressure. The liquefied air is then subjected to fractional distillatio..

Methanal (Formaldehyde) - It is manufactured by dehydrogenation or air oxidation of methanol in the presence of heated metallic copper or silver catalyst or by oxidation of methane with air in the presence of various metallic oxide catalyst..

As we know that we cannot live without air even for a single minute. We live in a vast ocean of air, which extends upwards for over 1000 km. Apart from providing us air to breathe, this blanket of air traps the sun's heat that is essential for life on t..

Air as a Mixture - As we know that we cannot live without air even for a single minute. We live in a vast ocean of air, which extends upwards for over 1000 km. Apart from providing us air to breathe, this blanket of air traps the sun's heat that is ..

Protoplast is a cell without cell wall. In plants, the cells are invariably surrounded by thick cell wall made of cellulose and pectin. During the process of tissue culture and using it for crop improvement, cell wall acts as a barrier to induce mutations or some times to develop the call..

NO 2 is allowed to enter the absorption tower from the lower end. The tower is packed with quartz pieces and water is sprinkled from the top. Here, NO 2 is absorbed into water in the presence of air to yield nitric acid...

Introduction - The Environment influences an organism's life in many ways. It is everything that surrounds an organism and it includes physical and biological components. The physical components of the environment are soil, water, air, light and temperature. These are termed as abiotic co..

The venous capillaries lining the alveoli have impure blood that has low concentration of oxygen and thus lower partial pressure (P O 2 in venous blood is 40mm of Hg). The oxygen of the air in the lungs has higher partial pressure (100mm of Hg) and therefore, easily diffuses into the bloo..

The capillaries lining the alveoli have impure blood which has low concentration of oxygen. So, the oxygen from the air easily diffuses into the blood through the thin barrier of the alveolus wall. Similarly since the concentration of carbon dioxide is quite high in the bl..
