air vapor pressure

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

Vapor Pressure of Solutions - Let us suppose a small amount of a non-volatile solute (sugar) is dissolved in a solvent (water). When evaporation of this solution takes place, only water evaporates as the other component (i.e., sugar) is non-volatile. The vapor pre..

In 1886 the French chemist Francois Marie Raoult carried out a series of experiments to study the vapor pressure of a number of binary solutions containing non-volatile as well as volatile non electrolyte solutes. On the basis of the results of the experiment he stated a l..

Ordinary air seems to be dry. It does not cause wetness on our body or clothes. However, you may have some idea about the huge quantity of rain, snow, dew, etc. that gets formed in a year throughout the world. All of it comes only from the air. Thus, the apparent dryness o..

The vapor density of chlorine = 35.5, which is nearly 2.5 times denser than air (Vapor density of air = 14.4..

Hydrogen sulphide has a vapor density of 17. The vapor density of air =14.4, i.e., it is 1.2 times denser than air..

A known mass W B of the non-volatile solute is dissolved in a known mass (W A ) of the volatile solvent to prepare a dilute solution and relative lowering of vapor pressure is determined experimentally. Knowing the molecular mass (M A ) of the solvent, molecular mass (M B ) of..

The vapor density of nitrogen is 14 (Vapor density of air = 14.4). Hence it is slightly lighter than air..

Air is pulled towards the surface by gravity and this exerts pressure on the Earth's surface. The pressure exerted by the gases of the atmosphere on the surface of the Earth is called atmospheric pressure..
