In thermodynamics, the enthalpy of mixing (also heat of mixing and excess enthalpy) is the enthalpy liberated or absorbed from a substance upon mixing. [1] When a substance or compound is combined with any other substance or compound, the enthalpy of mixing is the consequence of the new interactions between the two substances or compounds. [ 1 ]

The therm (symbol, thm) is a non-SI unit of heat energy equal to 100,000 British thermal units (BTU), [1] and approximately 105 megajoules, 29.3 kilowatt-hours, 25,200 kilocalories and 25.2 thermies. One therm is the energy content of approximately 100 cubic feet (2.83 cubic metres) of natural gas at standard temperature and pressure .
Zinc is required for the function of over 300 enzymes and 1000 transcription factors, [10] and is stored and transferred in metallothioneins. [194] [195] It is the second most abundant trace metal in humans after iron and it is the only metal which appears in all enzyme classes. [12] [10]
January averages 44.8 °F (7.1 °C), with temperatures in the suburbs slightly cooler due largely to the urban heat island effect. Lows at or below freezing can be expected 36 nights annually, [ 126 ] but the last occurrences of temperatures below 10 °F (−12 °C) were December 24, 2022 , [ 126 ] and January 2014 , eight years apart.
It was the fifth tallest wood construction structure in Germany. It was built in 1931 and was a popular place for day-trippers until it burned down in 2017. A faithful reconstruction has been opened to the public on 12 October 2020, exactly three years after the original's destruction. [89]
Monster High is an American CGI-animated teen monster fantasy [2] [3] comedy [1] television series based on the eponymous fashion doll franchise of the same name and its 2022 television film by Mattel and Mattel Television respectively, that aired on Nickelodeon in the United States and globally from October 6, 2022, to October 26, 2024.
