April 8, 2025Charles Law Formula: On increasing the temperature, the gas expands, and volume increases. For example, an inflated balloon expands in size on increasing in temperature, which may lead to the bursting of the balloon. Then, is the temperature and volume related to each other? What happens to the volume of the gas when we increase the temperature or temperature is kept constant?
You will quench the thirst for all these answers in this article, Charles law formula. In this article, you will deal with Charles law, its equation, derivation of equation, graph, practical application, numerical, etc. You will also derive combined gas law from Boyles and Charles law.

Let
For
For t degree rise in temperature, volume increases
Therefore, volume at
According to the mathematical form of Charles Law:
But
Therefore,
Thus,
Hence, Charles Law can also state that the volume of a given mass of gas is directly proportional to the absolute or Kelvin temperature at constant pressure.
Let
An interesting application of the Charles law is the use of hot air balloons in sports and also for meteorological observations. According to the law, the gases expand on heating. Since the mass of gas remains unchanged; therefore, the number of molecules per unit volume, that is, the density of the gas, decreases on heating. Hence, hot air is less dense than cold air. This enables the hot air balloons to rise up by displacing the cooler air of the atmosphere.
Boyle’s law states that “The volume of a given mass of a gas is inversely proportional to its pressure provided the temperature remains constant”. Mathematically, Boyle’s law is expressed as:
Or
By rearranging the equation, we get
The effect of pressure on the volume of gas at a constant temperature can be calculated with the help of Boyle’s law. The effect of temperature on the volume of the gas at constant pressure can be calculated by Charles Law. The combined effect of temperature and pressure on the volume of the gas is given by the combined gas law. Let the volume of a certain mass of a gas change from
Step 1: Suppose the volume of a given mass of a gas changes from
