what is absolute pressure

An increase in pressure increases the solubility of a gas. For example, aerated water bottles contain carbon dioxide gas under pressure..

A high pressure favors the process. Thus, the optimum pressure of 1.5 - 2 atm. is maintaine..

Some chemical reactions need very high pressure to proceed. For e.g., in the commercial manufacture of ammonia from nitrogen and hydrogen by Haber's process, a pressure of over 200 atmosphere is required, in presence of a catalyst iron and a temperature of 450oC to 500..

Pins and nails have pointed ends so that, when a pin is pressed, high pressure is applied on the surface with lesser force, as area is smal..

Pressure - When a force is applied on a surface in a direction perpendicular to the surface, the force is called thrust. Pressure on a solid surface is the thrust per unit area of the surface. Pressure is a scalar quantity. The SI unit of Pressure is N m - 2 ..

Solubility of a gas in a liquid increases with the increase in partial pressure of the gas above the solution. Quantitatively, this is governed by Henrys law, which states that at constant temperature. The mass of a gas dissolved in a given volume of the liquid is directly proportional ..

When a force is applied on a surface in a direction perpendicular to the surface, the force is called thrus..

Absolute error = true value - measured val..

Wall pressure is the pressure which is exerted by the rigid and elastic cell wall and is equal and opposite to turgor pressure..

The Good and the Bad ........... Peer pressure is when friends persuade you to doing something against your will. Peer Pressure can be broken down into two areas; bad peer pressure and good peer pressure..
