Chhattisgarh Pre Engineering Test has chemistry as its important subject and for that the preparation has to be done in a way that the competing power as per the level is maintained. The applicants need to study all the syllabus of the Chemistry subject and then practice the questions of each topic so that you have hands on each and everything. For this CGPET Chemistry Previous Papers are given below and can be used for your practice for the exam.
Q1: Helium- oxygen mixture is used by deep sea divers in preference to nitrogen- oxygen mixture due to-
- Nitogen is much more soluble in blood than helium
- Nitrogen is much less soluble in blood than helium
- Due to high pressure deep under the sea nitrogen and oxygen react to give poisonous nitric oxide
- Nitrogen is water soluble
