What is the Charles’s Law Calculator?

The Charles’s Law Calculator helps you find the relationship between the volume and temperature of a gas when pressure is kept constant. According to Charles’s Law, the volume of a gas is directly proportional to its absolute temperature. This calculator allows you to leave one value blank—initial volume (V₁), initial temperature (T₁), final volume (V₂), or final temperature (T₂)—and it will calculate the missing value instantly using the correct gas law formula. This tool makes solving gas problems easier for students, teachers, and anyone working with chemistry or physics.

How to Use:

1. Enter Initial Volume (V₁): Type the starting volume of the gas.
2. Enter Initial Temperature (T₁ in K): Input the initial temperature in Kelvin.
3. Enter Final Volume (V₂): Type the final volume if known, or leave it blank if it’s the value you want calculated.
4. Enter Final Temperature (T₂ in K): Type the final temperature or leave it blank if you want the calculator to find it.
5. Click “Calculate”: The calculator will determine the missing value based on Charles’s Law.
6. Review the Result: Use the displayed value for your chemistry calculations or assignments. Ensure only one field is left blank for accurate results.
