The law describing realtionship between P and V of ideal gas at constant temperature is called..........

Explanation

To solve the question, we need to identify the law that describes the relationship between pressure (P) and volume (V) of an ideal gas at a constant temperature. Here’s a step-by-step breakdown:

### Step 1: Understand the Ideal Gas Equation
The ideal gas equation is given by:
\[ PV = nRT \]
where:
- \( P \) = pressure of the gas
- \( V \) = volume occupied by the gas
