Question: What Is The Formula For Gay-Lussac’s Law?
Gay-Lussac’s Law is a special case of the ideal gas law. This law only applies to ideal gases held at a constant volume allowing only the pressure and temperature to change.
Answer: Gay-Lussac’s Law is expressed as:

Pi/Ti = Pf/Tf

where
Pi = initial pressure
Ti = initial absolute temperature
Pf = final pressure
Tf = final absolute temperature

It is extremely important to remember the temperatures are absolute temperatures measured in Kelvin, NOT °C or °F.
