Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. Isopropanol vapor pressure (logarithmic scale) vs temperature. Drawn using data published in [ 2 ] [ 3 ]
This is illustrated in the vapor pressure chart (see right) that shows graphs of the vapor pressures versus temperatures for a variety of liquids. [7] At the normal boiling point of a liquid, the vapor pressure is equal to the standard atmospheric pressure defined as 1 atmosphere, [ 1 ] 760 Torr, 101.325 kPa, or 14.69595 psi.
If an alcohol thermometer utilizes a combination of ethanol, toluene, and pentane, its lower temperature range may be extended to measure temperatures down to as low as −200 °C (−328 °F). [3] However, the measurement temperature range c. −200 °C to 78 °C, is highly dependent upon the type of alcohol used.
1-Butanol occurs naturally as a minor product of the ethanol fermentation of sugars and other saccharides [6] and is present in many foods and drinks. [ 7 ] [ 8 ] It is also a permitted artificial flavorant in the United States, [ 9 ] used in butter, cream, fruit, rum, whiskey, ice cream and ices, candy, baked goods, and cordials. [ 10 ]
Temperature-dependency of the heats of vaporization for water, methanol, benzene, and acetone. In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.
U.S. President-elect Donald Trump shakes hands with Argentine President Javier Milei at the America First Policy Institute (AFPI) gala at Mar-A-Lago in Palm Beach, Florida, U.S., Nov. 14, 2024.
The annotation, d a°C/b°C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4 °C, density of water is 0.999972 g/mL.
