Explain why a gas bubble released at the bottom of a lake grows in size as it rises to the surface of the lake.

Explanation

To explain why a gas bubble released at the bottom of a lake grows in size as it rises to the surface, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pressure at Depth**:
- At the bottom of the lake, the gas bubble is subjected to a high pressure due to the weight of the water above it. The total pressure (P) on the bubble can be expressed as:
\[
P = P_0 + h \rho g
