Question

Assertion : Thermodynamic process in nature are irreversible.
Reason : Dissipative effects cannot be eliminated

• A. Both assertion and reason are true and reason is the correct explanation of assertion
• B. Both assertion and reason are true but reason is not the correct explanation of assertion
• C. Assertion is true but reason is false
• D. Both assertion and reason are false

Answer 1

Answer: (A)

The thermodynamic 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.
