Why is mercury used in barometers?

Feb 18, 1977 ... In this paper, we con sider the saturated-vapor pressure of the hydrogens from 4.2 to 30 K. The vapor pressure along the solid- gas and liquid- ... Calculate partial pressures and total vapor pressure of the liquid. The vapor pressure of each component at 58.4°F can be determined using Antoine's ... Jun 14, 2023 ... My conclusion is that because 0C is the triple point of water, then all three phases coexist, so that is where the vapor pressure comes from. Water's saturated vapour pressure is about 20 mmHg at this temperature. A high vapour pressure means that the liquid must be volatile - molecules escape from ... must be removed from the wellhead, crude oil, or natural gas condensates so that the liquid product can meet the typical specifications such as vapor pressure ... Nov 14, 2020 ... At that point the solid, liquid and vapour are all in equilibrium so the solid has both a melting point and a vapour pressure. At the triple ... 7 days ago ... Final Answer: The temperature at which the vapor pressure of liquid nickel is 2.500 Torr can be found using the Clausius-Clapeyron equation and ... Nov 6, 2009 ... The vapour pressure is the pressure at which a liquid and its vapour are in equilibrium at a given temperature. The vapor pressure is a measure of the presure (force per unit area) exerted by a gas above a liquid in a sealed container. At 70°F (21.1°C) the cylinder contains both liquid and gas. Cylinder pressure, or the “vapor pressure” of the gas, is directly affected by ambient temperature.
