The percentage change in the volume of the given mass of a gas at constant temperature is 50% (increases). Calculate the percentage change in the presure of the gas.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the Relationship Between Pressure and Volume
According to Boyle's Law, for a given mass of gas at constant temperature, the product of pressure (P) and volume (V) is constant:
\[ P \times V = \text{constant} \]
This means that if the volume increases, the pressure must decrease, and vice versa.
