The volume of air increases by 2% in its adiabatic expansion. Calculate the percentage decrease in pressure.

Explanation

To solve the problem of calculating the percentage decrease in pressure when the volume of air increases by 2% during adiabatic expansion, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Adiabatic Process**:
In an adiabatic process, the relationship between pressure (P) and volume (V) is given by the equation:
\[
P V^\gamma = \text{constant}
