500 ml of air at 760 mm Hg pressure were compressed to 200 ml. What will be new pressure, if the temperature remains constant? 

Explanation

To solve the problem, we can 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 mathematically expressed as:

\[ P_1 V_1 = P_2 V_2 \]

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