Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: Thermodynamic process innate are irreversible. Reason: Dissiparive effects cannot eliminated.A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true but reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
Correct Answer: A
Solution :
The thermodynamics process is irreversible, as there always occurs a loss of energy due to energy spent in working against the dissipative force which is not recovered back. Other irreversible process also occurs in nature such as friction where extra work is required to cancel out the effect of friction.
