There exist two different spin isomers of hydrogen diatomic molecules that differ by the relative spin of their nuclei. In the orthohydrogen form, the spins of the two protons are parallel and form a triplet state with a molecular spin quantum number of 1 (12+12); in the parahydrogen form the spins are antiparallel and form a singlet with a molecular spin quantum number of 0 (1212). At standard temperature and pressure, hydrogen gas contains about 25% of the para form and 75% of the ortho form, also known as the "normal form". The equilibrium ratio of orthohydrogen to parahydrogen depends on temperature, but because the ortho form is an excited state and has a higher energy than the para form, it is unstable and cannot be purified. At very low temperatures, the equilibrium state is composed almost exclusively of the para form. The liquid and gas phase thermal properties of pure parahydrogen differ significantly from those of the normal form because of differences in rotational heat capacities, as discussed more fully in spin isomers of hydrogen. The ortho/para distinction also occurs in other hydrogen-containing molecules or functional groups, such as water and methylene, but is of little significance for their thermal properties.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What state are the protons in when in the orthohydrogen form?
Ah, so.. triplet state

Better acquaintance with Greek and Roman technical writings also influenced the development of European science (see the history of science in the Renaissance). This was despite what A. C. Crombie (viewing the Renaissance in the 19th-century manner as a chapter in the heroic March of Progress) calls "a backwards-looking admiration for antiquity", in which Platonism stood in opposition to the Aristotelian concentration on the observable properties of the physical world. But Renaissance humanists, who considered themselves as restoring the glory and nobility of antiquity, had no interest in scientific innovation. However, by the mid-to-late 16th century, even the universities, though still dominated by Scholasticism, began to demand that Aristotle be read in accurate texts edited according to the principles of Renaissance philology, thus setting the stage for Galileo's quarrels with the outmoded habits of Scholasticism.

Ah, so.. technical writings

In Estonian, nouns and pronouns do not have grammatical gender, but nouns and adjectives decline in fourteen cases: nominative, genitive, partitive, illative, inessive, elative, allative, adessive, ablative, translative, terminative, essive, abessive, and comitative, with the case and number of the adjective(s) always agreeing with that of the noun (except in the terminative, essive, abessive and comitative, where there is agreement only for the number, the adjective being in the genitive form). Thus the illative for kollane maja ("a yellow house") is kollasesse majja ("into a yellow house"), but the terminative is kollase majani ("as far as a yellow house"). With respect to the Proto-Finnic language, elision has occurred; thus, the actual case marker may be absent, but the stem is changed, cf. maja majja and the Pohjanmaa dialect of Finnish maja majahan.

Ah, so..
unanswerable
