What is the Gay-Lussac’s Law Calculator?

The Gay-Lussac’s Law Calculator is a tool that helps you calculate the relationship between pressure and temperature of a gas when volume is constant. According to Gay-Lussac’s Law, the pressure of a gas is directly proportional to its absolute temperature. This calculator allows you to determine one unknown value—initial or final pressure (P₁ or P₂) or initial or final temperature (T₁ or T₂)—by entering the other three known values. It simplifies manual calculations, making it easier for students and professionals to solve gas law problems accurately.

How to Use:

1. Enter Initial Pressure (P₁): Type the starting pressure of the gas.
2. Enter Initial Temperature (T₁ in K): Input the gas temperature in Kelvin at the initial state.
3. Enter Final Pressure (P₂): Provide the final pressure if known, or leave blank if this is what you want to calculate.
4. Enter Final Temperature (T₂ in K): Provide the final temperature if known, or leave blank if this is what you want to calculate.
5. Click “Calculate”: The calculator will determine the missing value and display it in the result box.
6. Review the Result: Use the calculated value for experiments, homework, or gas law problem-solving. Ensure only one field is left blank for accurate results.
