Hydrogen is a poor conductor of heat as compared to other gases.
Generally, the molecules of gases are very distant from each other.
Therefore, they are poor conductors of heat and electricity.
The exception is hydrogen(H2) and helium(He) gases.
Hydrogen has the highest thermal conductivity among all other gases available.
The thermal conductivity of hydrogen is dependent on temperature.
If it is cold, it can act as a superconductor and if it is hot, it becomes highly conductive.
I.e. Hydrogen is not a poor conductor of heat in comparison to other gases.
Hence, The given statement is false
