Is the melting point of hydrogen high or low?
Hydrogen has the second lowest boiling point and melting points of all substances, second only to helium. Hydrogen is a liquid below its boiling point of 20 K (–423 ºF; –253 ºC) and a solid below its melting point of 14 K (–434 ºF; –259 ºC) and atmospheric pressure. Obviously, these temperatures are extremely low.
Do hydrogen bonds have low melting points?
The presence of hydrogen bonding will lift the melting and boiling points. The larger the molecule the more van der Waals attractions are possible – and those will also need more energy to break.
Does hydrogen have a high melting point?
-434.5°F (-259.2°C)

Why does hydrogen have a lower boiling point than water?
So, to boil liquid water, all hydrogen bonds have to be broken and it requires a large amount of energy. This isn’t the case in HF; all hydrogen bonds need not to be broken, and therefore a lesser amount of energy is required. So HF boils at a much lower temperature as compared to water.
What is the melting point for hydrogen?
Why does hydrogen iodide require more energy to melt than hydrogen chloride?
Explanation: Given its polarizability, the diffuse electron cloud of the HI molecule allows more effective (i.e. more attractive) intermolecular interaction. Given this enhanced intermolecular interaction, HI should have a higher boiling point/melting point than HCl .
Why do materials containing hydrogen have high melting and boiling points?
Therefore, compounds containing hydrogen bonds require more energy to break the attraction between molecules than a nonpolar compound that only has London dispersion forces. Thus, the presence of hydrogen bonds increases the melting point of a compound.
Why does water have a higher melting point than hydrogen fluoride?
Each HF molecule possesses three lone pairs of fluorine and one hydrogen. Water molecules form a bulky molecule and it is very difficult to break its bonds. To break all its bonds, a large amount of the energy is required. Thus, $H2O$ has a higher boiling point than HF.
What is the boiling point of hydrogen peroxide?
