vapor pressure of liquids

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

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 pressure of the solution is found to be less th..

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 law kno..

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

It is a simple pressure gauge and it measures differences in pressure exerted at the two ends of the apparatus. It is called manometer. The mouth of a thistle funnel is tightly covered with a thin plastic shee..

Liquids that have weak intermolecular forces are more volatile and have a higher vapor pressure. For e.g., vapor pressure of ethyl alcohol is greater than that of the wat..

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

Transmission of Pressure in Liquids - Transmission of pressure in liquid Pascal's Law Pascal's law states that pressure applied to an enclosed liquid, is transmitted equally to every part of the liquid. This can de demonstrated u..
