Web14 dec. 2024 · When looking at the table above, the large specific heat capacity of hydrogen of 14.3 kJ/ (kg⋅K) is particularly striking. Because of this high value, hydrogen is also used for cooling because it changes its temperature only to a small extent when heated by the material to be cooled – so it stays cold for a very long time! WebLiquid hydrogen (H 2 (l)) is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H 2 form. [4] To exist as a liquid, H 2 must be cooled below its critical point of 33 K. However, for it … Web9 sep. 2024 · Indeed below about 60 K the molar heat capacity of hydrogen drops to about 3 2 R T - just as if it had become a monatomic gas or, though still diatomic, the molecules were somehow prevented from rotating. The molar heat capacities of nonlinear polyatomic molecules tend to be rather higher than predicted. peter fenwick the art of dying pdf
