4.2 Kelvin is -268.95 degrees Celsius.
Liquid Helium is colder than Liquid Hydrogen.
Helium has the lowest boiling point of any known substance, at -268.9 degrees Celsius.
Helium melting point: -272,2 0C Rhenium boiling point: 5 596 0C
The boiling point of Mercury is 357 degrees Celsius.
At 30 degrees Celsius, bromine is in a liquid state. Bromine has a melting point of -7.2 degrees Celsius and a boiling point of 58.8 degrees Celsius, so at 30 degrees Celsius it would be in a liquid state.
The boiling point of liquid helium is -268.9 degrees Celsius.
Yes, liquid helium boiling is a physical property. Boiling point is a physical property that describes the temperature at which a substance changes from a liquid to a gas. In the case of helium, its boiling point is very low at -268.9 degrees Celsius.
The boiling point is a little over 4 Kelvin; that is, at lower temperatures it is a liquid.
The melting point of helium is -272.2 degrees Celsius, and the boiling point is -268.9 degrees Celsius. Helium is a unique element because it remains a liquid at very close temperatures to absolute zero.
Helium (He)Boiling points: 4.22 K, −268.93 °C, −452.07 °F
Of the ELEMENTS, Helium has both the lowest melting point and the lowest boiling point. Under normal pressure, Helium is only a liquid between -272C and -269C. That first number is less than one degree above absolute zero, so there's not much room for any compound to be a colder liquid.
Liquid Helium is colder than Liquid Hydrogen.
Helium doesnt have a melting point as it will never form solid.
Helium has the lowest boiling point of any known substance, at -268.9 degrees Celsius.
The melting point of helium is 1.15 K and its boiling point is 4.22 K. So in oC they would be: Melting Point: 1.15 - 273.15 = -272.00 oC Boiling Point: 4.22 - 273.15 - 268.93 oC
The boiling point of water is at 100 degrees Celsius
