(Answer the following questions briefly and to the point :)
What is the relation between the pressure and the kinetic energy per unit volume of gas ?

Explanation

To find the relation between the pressure (P) and the kinetic energy per unit volume (KE) of a gas, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Kinetic Energy of a Gas:**
The kinetic energy (KE) of an ideal gas can be expressed as:
\[
KE = \frac{3}{2} nRT
