A steel cylinder of intemal volume 20 litres is filled with hydrogen at 29 atmospheric pressure. If hydrogen is used to fill a balloon at 1.25 atmospheric pressure at the same temperature, what volume will the gas occupy?

Explanation

To solve the problem step by step, 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 expressed mathematically as:

\[ P_1 V_1 = P_2 V_2 \]

Where:
- \( P_1 \) = initial pressure of the gas (in the steel cylinder)
- \( V_1 \) = initial volume of the gas (in the steel cylinder)
- \( P_2 \) = final pressure of the gas (in the balloon)
