definition of absolute pressure

Gay-lussac's law states that at fixed volume, for a given amount of ideal gas the pressure(P) is directly proportional to the absolute temperature(T). Which of the following curves represents the relationship between P and T. => Graph B or Graph C or Graph A..

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

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

Increase of pressure on the surface of a liquid increases the surface tension. Such effects are not large. The following two important phenomena are due to surface tensi..

Pressure - There are many situations in which effects of a force are better described in terms of force per unit area i.e. 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 or Pascal (Pa..

There are many situations in which effects of a force are better described in terms of force per unit area i.e. pressure..

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..
