Chas a constant value depending only on the nature of the liquid Dhad a constant value at constant temperature Submit How is the vapour pressure of a liquid in a closed container affected when the quantity of liquid is doubled at constnat temperature?
To understand why the vapor pressure of a liquid decreases when a non-volatile solute is added, we can break down the explanation into several steps: 1. Definition of Vapor Pressure: - Vapor pressure is the pressure exerted by the vapor in equilibrium with its liquid at a given temperature...

Simultaneous measurements of the vapour pressure of liquid oxygen and of the resistance of a number of platinum thermometers were carried out in two different apparatuses. The platinum thermometers were previously calibrated on the gas thermometer scales of NBS, PSU, PRMI and NPL respectively. ...
摘要: The vapour pressure of liquid nitrogen has been measured between 176°C and 148°C. The results are represented as a function of temperature by a formula, containing four constants.DOI: 10.1016/S0031-8914(53)80003-0 被引量: 73 ...

THE usual method of measuring absolute temperature T in the liquid-helium range is to measure the vapour pressure p of the liquid-helium bath and convert it by means of an empirically determined p-T relation. In the past, confusion has sometimes arisen owing to the existence of several ...
not all liquids produce a flammable vapour. As the temperature of a flammable liquid increases, the vapour pressure rises and, as a result, the concentration of flammable vapour in the air also increases. Should the temperature of the liquid exceed the flash point, the threat of an explosion ...
