This Charles law calculator can find the missing quantities in the Charles law of ideal gas. The formula for each quantity appears on the side of the calculator.

What is Charles’s law?

Charles's Law is an ideal gas law where at constant pressure; the volume of an ideal gas is directly proportional to its absolute temperature.

Jacques Charles studied the relationship between volume (V) and temperature (T) of a confined gas at constant pressure and saw how gas tends to increase in volume when heated.

It was first published by French natural philosopher Joseph Louis Gay-Lussac in 1802, although he credited the discovery to unpublished work from the 1780s by Jacques Charles.

Charles law formula:

Charles observed that the ratio of volume and temperature remains nearly constant which can be given as:

Gas Equation: Vi/Ti = Vf/Tf

or

Vf/Vi = Tf/Ti

or

ViTf = VfTi

where,

• Vi = Initial Volume
• Ti = Initial Temperature
• Vf = Final Volume
• Tf = Final Temperature

How to calculate the temperature of gas using the Charles law equation?

Example:

Calculate the Final Temperature (Tf) by using the Charles’ Law Calculator.

Initial Volume (Vi) = 25 L

Initial Temperature (Ti) = 5 K

Final Volume (Vf) = 15 L

Solution:

Apply Formula:

Gas Equation: Vi/Ti = Vf/Tf or Vf/Vi = Tf/Ti or ViTf = VfTi

Tf = [(15) * (5)] / 25

Final Temperature (Tf) = 3 K
