- ADissolution of $CuS{O_4}$ in water
- BReaction between ${H_2}$ and ${O_2}$ to form water
- CWater flowing down hill
- ✓Flow of electric current from low potential to high potential
✓
Answer
Correct option: D.
Flow of electric current from low potential to high potential
d
The physical or chemical processes which do not proceed by its own in a particular direction and requires outside help is called a non-spontaneous process. Therefore, flow of heat from a cold body to a hot body is a nonspontaneous process as it requires external work as per Clausius
