Name the factor on which emf of a cell depends.

Explanation

To answer the question about the factors on which the electromotive force (EMF) of a cell depends, we can break it down into several key points:

### Step-by-Step Solution:

1. **Definition of EMF**:
- EMF, or electromotive force, is the potential difference generated by a cell when no current is flowing. It is essentially the energy provided by the cell per unit charge.

2. **Temperature**:
