liquid nitrogen pressure

Suppose a horizontal area A (m 2 ) is supporting a column of liquid of height h (m) and density d (kgm - 3 ..

>If mole fraction is used to represent the solubility of the gas in the solution, th..

We can investigate pressure in a liquid by using the apparatus shown in figure belo..

Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperatur..

Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperature. fig 3.3 In illustrations 1a and 1b, the liquid and vapor states of a given substance are represented..

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..

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..

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..
