Charles Law Calculator

What is Charles's Law?

Charles's Law states that the volume of a gas is directly proportional to its absolute temperature when pressure is held constant. This means that if the temperature of a gas increases, its volume will also increase, and vice versa.

How to Use the Calculator

1. Enter the Initial Volume (V₁) of the gas in liters.
2. Enter the Initial Temperature (T₁) of the gas in degrees Celsius (°C).
3. Enter the Final Temperature (T₂) of the gas in degrees Celsius (°C).
4. Click the Calculate button to calculate the final volume (V₂).
5. The result will be displayed in liters.

Example

If you have a gas with an initial volume of 2 liters at 25°C, and you want to know its volume at 50°C, you would:

1. Enter 2 in the Initial Volume field.
2. Enter 25 in the Initial Temperature field.
3. Enter 50 in the Final Temperature field.
4. Click Calculate.
5. The calculator will display the final volume as 4 liters.

Important Notes

• Ensure that all temperature values are in degrees Celsius (°C).
• The initial temperature (T₁) cannot be zero to avoid division by zero errors.
• This calculator assumes that the pressure remains constant during the temperature change.
