Why can't scientists collect temperature and volume data for an enclosed gas at temperatures near absolute zero.

Because a phenomenon called Bose-Einstein condensation can occur.

Explanation:

Bose-Einstein condensation is a phenomenon that can occur when a scientist works with temperatures close to absolute zero. In this situation, the material being analyzed is compacting, condensing, in a way that could become a large, single atom. When this happens, it is impossible to collect accurate temperature and volume data. This phenomenon occurs in the processes of temperature decay and physical state changes, in which the gas becomes liquid, the liquid becomes solid, and, in this way, the solid would tend to have its particles more and more united.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
