Ethan made a diagram to compare examples of the first and second laws of thermodynamics. What belongs in the areas marked X and Y?

First law of thermodynamics:

It states that "Energy neither be created nor it can be destroyed". simply it converts one form of energy into another form. It is also known as "law of conservation of energy"

Limitations of First law

It doesn't provide a clear idea about the direction of transfer of heat. It doesn't provide the information that how much heat energy converted inti work. Its not given any practical applications.

II law of thermodynamics:

It states that "the total entropy of the system can never decrease over time"

It is strongly proved by two laws, they are

1. Kelvin-plank statement:

He stated that "any engine does not give 100% efficiency". It violates the Perpetual motion of machine II kind (PMM-II).

2. Classius statement:

It states that "Heat always flows from high temperature body to low temperature body, without aid of external energy".

Also it stated that " Heat can also be transferred from low temperature body to high temperature body, by the aid of an external energy".

Applications of II law:

Refrigeration &Air conditioning, Heat transfer, I. C. engines, etc.

The answer is D.

Explanation:

I just took the quiz.
