![]() The normal boiling point of water is 100° C and the standard boiling point in 99.6° C. The boiling temperature at 1 atm.pressure is called as the normal boiling point while the boiling point at 1 bar is called the standard boiling point. At the boiling point, the vapor pressure is equal to the liquid pressure. When bulk vapors evaporate to the surroundings at a specific temperature, then that temperature is called the boiling point. In closed vessels, the heating produces vapors which exert pressure on the container of the walls while when heated in open vessels, the vapors evaporate to the surroundings from the surface. Behaviour of Real Gases – Deviations From Ideal Behaviour.Browse more Topics under States Of Matter The whole phenomenon of vapor formation solely depends on the temperature and hence tends to increase with the increasing temperature. ![]() The vapor pressure at the point of equilibrium is known as the equilibrium vapor pressure or saturated vapor pressure. Gradually, an equilibrium between the liquid phase and the vapor phase is established. ![]() Initially, the vapor pressure increases but after some time it becomes constant. Liquids show the unique property of turning into vapors, as soon as the temperature rises! Generally, vapors from the aqueous substance occupy the walls of the unfilled part of the container and exert a pressure on the walls of that container, this pressure is called the vapor pressure. When a liquid is filled in a container, its walls are occupied by the vapors from that liquid. Apart from the above characteristics, liquids also show the following properties: Vapour Pressure When the physical conditions change the basic characters of liquids also undergo a drastic change. ![]() At normal conditions of temperature, pressure, and volume liquids generally, show the above-mentioned features. ![]()
