What will happen to the potential energy of an air bubble in water when it rises in water ?

Explanation

To solve the question "What will happen to the potential energy of an air bubble in water when it rises in water?", we can break it down into several steps:

### Step-by-Step Solution:

1. **Understanding Potential Energy**:
Potential energy (U) in a gravitational field is given by the formula \( U = mgh \), where \( m \) is the mass, \( g \) is the acceleration due to gravity, and \( h \) is the height above a reference point.

**Hint**: Remember that potential energy is related to height in a gravitational field.
