Question
Two pupils Ram and Shyam have taken lime water in a vessel, as shown in the figure. Ram is inhaling air from straw A and Shyam is blowing air through straw B. In which case lime water turns milky faster and Why?
- In case of Ram as inhaled air contains more CO2 than exhaled air
- In case of Shyam as exhaled air contains more CO2 than inhaled air
- In case of Ram as inhaled air contains more water vapour than exhaled air
- In both the cases lime water turns milky in same time
The correct answer is: In case of Shyam as exhaled air contains more CO2 than inhaled air

Differentiation is the process of determining a function's derivative. The derivative is the rate at which x changes in relation to y when x and y are two variables. A constant function has zero derivatives. For instance, f'(x) = 0 if f(x) = 8. So the derivative function is odd.
