Science in SSC CGL General Awareness spans Physics, Chemistry, and Biology basics — often testing precise factual recall rather than deep conceptual understanding. This article compiles real, verified Science questions extracted directly from official Tier 1 papers.
10 Real PYQ Questions
Q1. Methane is a colourless, odourless, non-toxic but flammable gas. What is its common name?
1. Blue vitriol 2. Laughing gas 3. Marsh gas 4. Heating gas
Show Answer
3. Marsh gas.
Q2. Who is the only scientist in the world to have won the Nobel Prize in Chemistry twice?
1. Madame Curie 2. Roger D. Kornberg 3. Linus Carl Pauling 4. Frederick Sanger
Show Answer
4. Frederick Sanger. He won in 1958 and again in 1980. (Marie Curie won two Nobel Prizes, but in different fields — Physics and Chemistry, not Chemistry twice.)
Q3. Flying Officer _____ of the Indian Air Force created history by becoming the first Indian woman to fly a solo fighter flight in a Russian-made MiG-21 fighter.
1. Bhawana Kanth 2. Anjali Gupta 3. Mohana Singh 4. Avani Chaturvedi

1. 8 2. 7 3. 10 4. 9
Show Answer
4. 9. This element is Fluorine.
Q6. In which year did Walther Flemming coin the term 'chromatin' for the stained substance found in the cell nucleus?
1. 1900 2. 1840 3. 1849 4. 1879
Show Answer
4. 1879.
Q7. In which year did Antoine Lavoisier publish 'Methods of Chemical Nomenclature,' which included rules for naming chemical compounds still in use today?

Show Answer
3. Cell wall.
Q9. Which actinide, discovered by Glenn T. Seaborg in 1940, is used as a heat source for sensitive electrical components in satellites, as well as a power source for satellites?
1. Curium 2. Plutonium 3. Nobelium 4. Americium
Show Answer
2. Plutonium.
Q10. Ethanoic acid is a synonym for which acidic liquid used in kitchens around the world as a basic seasoning in food preparation?
1. Apple Juice 2. Vanillin 3. Caustic Soda 4. Vinegar
Show Answer
4. Vinegar.
Frequently Asked Questions
Q1. Is Science harder to prepare than Polity or History?
Not inherently — it tests precise factual recall similar to the other GA subjects, though some questions (like Q5 above) require basic conceptual understanding of periodic table structure rather than pure memorization.
Q2. Should I prioritize Physics, Chemistry, or Biology within Science?
Based on this dataset, all three appear with reasonable frequency — a balanced approach across all three tends to work better than heavily favoring one.
Q3. How current does my Science knowledge need to be?
Most Science GA questions test foundational, stable facts (like Q1, Q4, Q8 above) rather than cutting-edge developments — a solid grasp of school-level Physics, Chemistry, and Biology covers most of what's tested.
