1.	Passage - VIII : In this passage five observation are given. Question are asked with reference to the givenobservations Observation (i) Gaseousoxygen is colourless whereas liquid and solid oxygen are coloured substance. Observation (ii) When O_(2) is cooled below a certain temperature its paramagnetic character decreases. Observation (iii) In ice H_(2)O molecules are H bonded Observation (iv) Ozone is responsible for tailing of Hg(l) Observation (v) O_(3)(g) is almost unavailable in lower atmosphere Reference to observation (v) O_(3)(g) is unavailable in lower atmosphere because -
Answer» at lower altitude`O_(3)`produced is decomposed to `O_(2)` due to the HIGHER temperature at lower temperature there is noise pollution, therefore `O_(3)` produced is decomposedto `O_(2)` `O_(3)(g)` is HEAVIER than air, hence availablein the coal mines in the lower altitude UV RADIATION of higher frequencies required for the dissociation of gaseous `O_(2)` to atomic oxygen, are unavailable SOLUTION :In the lower altitude UV radiation of higher frequencies required for the dissociation of gaseous`O_(2)` to atomic oxygen, are unavailable
