The biliong point of hydrogen is -252,87 0C. The melting point of hydrogen is -259,14 0C.
Melting: -259.14 C Boiling: -252.87 C
hydrogen
hydrogen bonding increases the intermolecular attractions and therefore increases the boiling point and melting point.
The freezing point (same as melting point) of H2 is 14.01 K (−259.14 °C, −434.45 °F)The boiling point of H2 is 20.28 K (−252.87 °C, −423.17 °F)
Water has a high melting point and boiling point because of hydrogen bonds
Hydrogen melts at -259.14 °C and boils at -252.87 °C
melting: -259.14 °C boiling: -252.87 °C to find it in degrees F, multiply by 1.8 and then add 32.
