MCQ
For a thermodynamics process to be reversible, the temperature difference between hot body and the working substance should be :
- ✓zero
- Bminimunm
- Cmaximum
- Dinfinity
✓
Answer
Correct option: A.
zero
In thermodynamics, a reversible process is a process whose direction can be "reversed" by inducing infinitesimal changes to some property of the system via its surroundings, while not increasing entropy. Throughout the entire reversible process, the system is in thermodynamic equilibrium with its surroundings, which means that the hot body and surroundings are at same temperature.
