During an adiabatic expansion, a gas obeys `VT^(3) =` constant. The gas must be

Options

A. Monoatomic
B. Diatomic
C. Polyatomic
D. Any of above

Explanation

To solve the problem, we need to analyze the given expression and the implications of the adiabatic process for the gas. The expression provided is \( V T^3 = \text{constant} \).

### Step-by-Step Solution:

1. **Understanding the Given Expression**:
We start with the expression \( V T^3 = \text{constant} \). This implies that the product of the volume \( V \) and the cube of the temperature \( T \) remains constant during the process.

2. **Relating Temperature and Pressure**:
