Charle's law states that the volume of gas for a fixed mass is directly proportional to the temperature. Sometimes, it is also called the law of volumes. t defines the relationship between volume and temperature of a gas at constant pressure.
Charles law is defined as the ratio of volume and temperature of a gas in a system that remains constant when the pressure is constant. The law indicates the behaviour of an ideal gas in an isobaric process.
According to the Charles law, the equation is V ∝ T.
V₁/T₁ = V₂/T₂
Where,
The formula to compute the final volume is V₂ = V₁ / T₁ * T₂
Final temperature is T₂ = T₁ / V₁ * V₂
Initial Volume V₁ = V₂ / T₂ * T₁
Initial Temperature T₁ = V₁ / V₂ * T₂
As per Charles law, the volume of gas is directly proportional to the temperature at constant pressure.
The statement is V∝T
So, V/T = constant = k
Let us take V₁ is the initial volume, T₁ is the initial temperature
The equation is V₁/T₁ = k --- (i)
If V₂ is the final volume, T₂ is the final temperature then equation is V₂/T₂ = k --- (ii)
By equating both equations
V₁/T₁ = V₂/T₂
Example:
Question: A gas occupies 220 cm^{3} at a temperature of 0 c and pressure of 760 mm Hg. What will be the volume at 110 C?
Answer:
Given that,
Initial volume V₁ = 220 cm^{3}
Initial temperature T₁ = 0 c = 0 + 273 = 273 k
Final temperature T₂ = 110 C = 110 + 273 = 383 K
Charle's law formula is V₁/T₁ = V₂/T₂
Final volume V₂ = V₁/T₁ * T₂
= (220/273) * 383
= 308.64
Therefore, final volume is 308.64 cm^{3}

The following graph between the temperature and volume of a gas at constant pressure is called the Isobar or Isoplestics and it is always a straight line. The graph of volume versus temperature at constant pressure is shown below temperature 273.15°C and it is the lowest possible temperature.
Some of the applications of Charle's law are provided here.
1. What is Charle's Law Equation?
The Charle's Law formula is V₁ * T₂ = V₂ * T₁ at constant pressure. Here, V₁, T₁ are initial volume and temperature, V₂, T₂ are final volume and temperature.
2. What is Charle's Law?
Charles law states that the volume of gas for a fixed mass is directly proportional to the temperature. In other words, if the gas expands then the temperature is increased.
