Answers :
1) Answer: a)
In chemistry and physics, the Avogadro constant, named after scientist Amedeo Avogadro, is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole.
2) Answer: b)
Isoprene, or 2 – methyl-1, 3 – butadiene, is a common organic compound with the formula CH₂=C−CH=CH₂. In its pure form it is a colorless volatile liquid. Isoprene is produced by many plants and animals and its polymers are the main component of natural rubber.
3) Answer: c)
Urea has a mass percent composition of 20% Carbon, 6.71% Hydrogen, 46.65% Nitrogen, and 26.64% Oxygen.
4) Answer: c)
- Acetic acid, systematically named ethanoic acid, is a colourless liquid organic compound with the chemical formula CH₃
- When undiluted, it is sometimes called glacial acetic acid. Vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water.
5) Answer: a)
The hormones responsible for beard growth are testosterone and dihydrotestosterone (DHT). While testosterone is responsible for hair follicle priming, DHT promotes the linear growth of facial hair.
6) Answer: d)

The reason ink leaks during flight is because the pressure in the airplane cabin drops as you leave the ground and go up into the air. This means the pressure in your pen is higher than the surrounding environment.
9) Answer: a)
Fan actually increases room temperature. While the fan operates in a closed room, the motion of the air molecules increases. The increase in the motion of the air molecules increases the rate of evaporation of sweat from our body. Due to this evaporation, we feel cool.
10) Answer: c)
