WebBecause the Kelvin degree is the same as the Celsius degree, the two reference temperatures for Celsius: the freezing point of water (0°C) and the boiling point of water (100°C) are 273.15°K and 373.15°K respectively. People also inquire as to what Kelvin melting freezing point is. The absolute zero temperature is 273.15° C or 459.67° F. In 1908, helium was first liquefied by Dutch physicist Heike Kamerlingh Onnes by cooling the gas to less than 5 K (−268.15 °C; −450.67 °F). [42] [43] He tried to solidify it, by further reducing the temperature, but failed, because helium does not solidify at atmospheric pressure. See more Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element with the symbol He and atomic number 2.
