Text Solution
AI Generated Solution
To find the surface energy of an air bubble of radius \( r \) inside a soap solution with surface tension \( T \), we can follow these steps:
### Step-by-Step Solution:
1. **Understand the Concept of Surface Energy**:
Surface energy is defined as the energy required to create a new surface. For a liquid surface, this energy is related to the surface tension and the surface area.
2. **Identify the Surface Area of the Bubble**:
