2.5 L of a sample of a gas at `27^(@)C and 1` bar pressure is compressed to a volume of 500 mL keeping the temperature constant, find the % increase in the pressure.

Explanation

To solve the problem, we will use Boyle's Law, which states that for a given mass of gas at constant temperature, the product of pressure and volume is constant. This can be represented mathematically as:

\[ P_1 \times V_1 = P_2 \times V_2 \]

Where:
- \( P_1 \) = initial pressure
- \( V_1 \) = initial volume
- \( P_2 \) = final pressure
