How can one effectively solve Gay-Lussac's Law in a practical scenario?

To effectively solve Gay-Lussac's Law in a practical scenario, you need to understand the relationship between pressure and temperature of a gas at constant volume. Use the formula P1/T1 P2/T2, where P1 and T1 are the initial pressure and temperature, and P2 and T2 are the final pressure and temperature. Make sure to convert temperature to Kelvin and pressure to the appropriate units. Then, plug in the values and solve for the unknown variable.
