Coal India Limited Mechanical engineering questions with answer
1. What is the importance of the Thermodynamics in the field of Mechanical Engineering?Â
All the mechanical engineering systems are studied with the help of thermodynamics. Hence it is very important for the mechanical engineers.
2. How many Laws of Thermodynamics are there?Â
There are three laws of the thermodynamics.
First Law: Energy can be neither created nor destroyed. It can only change forms.In any process in an isolated system, the total energy remains the same.
Second Law: When two isolated systems in separate but nearby regions of space, each in thermodynamic equilibrium in itself, but not in equilibrium with each other at first, are at some time allowed to interact, breaking the isolation that separates the two systems, and they exchange matter or energy, they will eventually reach a mutual thermodynamic equilibrium. The sum of the entropies of the initial, isolated systems is less than or equal to the entropy of the final exchanging systems. In the process of reaching a new thermodynamic equilibrium, entropy has increased, or at least has not decreased.
Third Law: As temperature approaches absolute zero, the entropy of a system approaches a minimum.
3. State Laws of conservation of energy?Â
According to the laws of conservation of energy, âenergy can neither be created nor be destroyed. It can only be transformed from one form to another.â
4. Is the boiler a closed system?Â
Yes definitely the boiler is a closed system.
5. What is Carnot engine?Â
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.
6. Which formula forms a link between the Thermodynamics and Electro chemistry?Â
Gibbs Helmholtz formula is the formula which forms the link between the thermodynamics and electromagnetism.
