(a) 1
(b) 10
(c) 100
(d) 1000
Correct Answer: (c) 100
Question from UPSC Prelims 2020 CSAT Paper
Explanation :
If 1 litre of water weighs 1kg ….
GIVEN CONVERSIONS:
1. Volume Conversion:
– 1 cubic millimeter = 10^-6 liters
– 1 liter = 10^6 cubic millimeters
2. Weight-Volume Relationship:
– 1000 grams (1 kg) = 10^6 cubic millimeters
CALCULATION:
1. To find volume for 0.1 grams:
– If 1000 grams = 10^6 cubic millimeters
– Then 1 gram = 10^3 cubic millimeters
– Therefore, 0.1 grams = 10^2 cubic millimeters
– 0.1 grams = 100 cubic millimeters
