Explain the physical significance of vanderWaals parameters.

Explanation

To explain the physical significance of the van der Waals parameters, we can break down the van der Waals equation and the roles of the parameters A and B step by step.

### Step-by-Step Solution:

1. **Understanding the van der Waals Equation**:
The van der Waals equation is given by:
\[
\left( P + \frac{a n^2}{V^2} \right) (V - nb) = nRT
