Assertion (A): Second law of thermodynamics is called the law of degradation of energy.
Reason (R): Energy does not degrade each time it flows through a finite temperature difference.
The correct answer is option 'C', where Assertion (A) is true but Reason (R) is false.
Explanation:
The second law of thermodynamics is a fundamental principle in physics that deals with the concept of entropy and the flow of heat. It states that in any natural process, the total entropy of an isolated system always increases over time or remains constant if the system is in equilibrium.
Second Law of Thermodynamics:
According to the second law of thermodynamics, energy spontaneously tends to flow from a higher temperature region to a lower temperature region until both regions reach the same temperature. This flow of energy is irreversible and results in the dissipation of energy.
Law of Degradation of Energy:
The law of degradation of energy is a concept derived from the second law of thermodynamics. It states that every time energy is transferred or transformed, some amount of it is dissipated or degraded into a form that is less useful or accessible for doing work.
Explanation of Assertion (A):
The second law of thermodynamics can be referred to as the law of degradation of energy because it describes the irreversible nature of energy transfer and transformation. With each energy transfer, some of the energy is lost in the form of heat, resulting in a decrease in the overall usefulness of the energy.
Explanation of Reason (R):
The reason provided in the question is incorrect. Energy does degrade each time it flows through a finite temperature difference. When energy flows from a higher temperature region to a lower temperature region, it is converted into heat, and some of the energy is dissipated in the process. This dissipation of energy is a result of the irreversibility of natural processes described by the second law of thermodynamics.
Conclusion:
In conclusion, Assertion (A) is true as the second law of thermodynamics can be referred to as the law of degradation of energy. However, Reason (R) is false as energy does degrade each time it flows through a finite temperature difference.
