WitrynaA pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water (deuterium oxide D 2 O) as its coolant and neutron moderator. PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium.The heavy water coolant is kept under pressure to avoid boiling, allowing it to reach higher … Witryna3. Para hydrogen is more stable than ortho hydrogen. Hence it is possible to get pure para hydrogen by cooling ordinary hydrogen to nearly 20 K. But it is never possible to get sample of more than 75% of ortho hydrogen. Hence this is a coorect statement. 4. In ordinary dihydrogen, both ortho and para hydrogen will be in equilibrium.

Ordinary hydrogen at room temperature is a mixture of:

WitrynaQuite apart from isotopes, it has been shown that under ordinary conditions hydrogen gas is a mixture of two kinds of molecules, known as ortho- and para-hydrogen, which differ from one another by the spins of their electrons and nuclei. Normal hydrogen at room temperature contains 25% of the para form and 75% of the ortho form.
