How is vapor pressure regulated for certain chemicals?

Vapor pressure is a measure of a liquid's volatility. A high vapor pressure usually is an indication of a volatile liquid, or one that readily vaporizes. B ... A liquid's vapour pressure is a vapour's equilibrium pressure above its liquid (or solid); that is, the vapour pressure resulting from a liquid (or solid) ... The boiling point of a liquid is the temperature at which its equilibrium vapor pressure is equal to the pressure exerted on the liquid by its gaseous ... The change from the gas phase to the liquid is called condensation. When the rate of condensation becomes equal to the rate of vaporization, neither the amount ... Chemical formula, CH ; Molecular weight, kg/k/mole, 16 ; Boiling point of liquid at atmospheric pressure, °C · -161.6 ; Specific gravity of vapour (Air=1), 0.6 ... Sep 28, 2010 ... Vapour Pressure In Hysys - posted in Chemical Process Simulation: Hi all, I am doing control valve sizing for liquid and pump sizing and i ... Dec 15, 2021 ... Note that vapor pressure increases as temperature increases. (3) NPSHR := Net Positive Suction Head Required to avoid cavitation. This quantity ... May 29, 2023 ... The normal boiling point of a substance is the temperature at which the substance changes from its liquid state to its gas state under a ... Jul 14, 2022 ... Because vapour pressure is a function of temperature, the flash point is the temperature that gives a vapour concentration that is equal to the ... Abstract. The vapour pressure of CO2 has been measured between − 56°C and + 3°C. The results are described by a semi-empirical formula. Special attention has ...
