Question

Statement (I) : There is entropy transfer both in heat transfer and work transfer.

Statement (II) : Both heat and work is energy in transition

1. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
2. Both Statement (I) and Statement (II) are individually true but Statement (II) is NOT the correct explanation of Statement (I)
3. Statement (I) is true but Statement (II) is false
4. Statement (I) is false but Statement (II) is true

Answer 1

Correct Answer - Option 4 : Statement (I) is false but Statement (II) is true

Concept:

→ Entropy transfer associated with work transfer (high grade energy) is always zero, as unavailable energy associated with work transfer is zero.

Hence statement 1 is false

→ Both heat and work can be transfer between system and surrounding once it crosses the boundary, hence heat and work are energy in transition and are path functions.

Hence statement 2 is true
