11. What is the Difference between a Generator and Inverter?

An inverter is only effective if there is already a source of electrical energy. It cannot generate its own. It can simply convert electrical energy that is already there. 

On the other hand, a traditional generator cannot make AC current into DC current.

12. What is the Difference between Quantitative and Qualitative Research?

Quantitative research involves gathering data that is absolute, such as numerical data, so that it can be examined in as unbiased a manner as possible.

Qualitative research may yield stories, or pictures, or descriptions of feelings and emotions. The interpretations given by research subjects are given weight in qualitative research, so there is no seeking to limit their bias. At the same time, researchers tend to become more emotionally attached to qualitative research, and so their own bias may also play heavily into the results.

13. What is the importance of the Thermodynamics in the field of Mechanical Engineering?

All the mechanical engineering systems are studied with the help of thermodynamics. Hence it is very important for the mechanical engineers.

14. Is the boiler a closed system?

Yes definitely the boiler is a closed system.

15. What is Carnot engine?

It was being designed by Carnot and let me tell you that Carnot engine is an imaginary engine which follows the Carnot cycle and provides 100% efficiency.

16. Which is the hardest compound known?

Diamond.

17. What is Hess Law?

According to the Hess law the energy transfer is simply independent of the path being followed. If the reactant and the product of the whole process are the same then same amount of energy will be dissipated or absorbed.

18. Which has more efficiency: Diesel engine or Petrol engines?

Off course Diesel engine has the better efficiency out of two.

19. What is Bending moment?

When a moment is applied to bend an element, a bending moment exists in the element

20. What are the points in the Stress Strain curve for Steel?

Proportional limit, elastic limit or yield point, ultimate stress and stress at failure.
