What is Gay Lussac's law?
A tyre blowout is a direct consequence of Gay Lussac’s Law. On a hot sunny day, as the temperature of the surrounding air rises, the pressure of the gas inside the tyre increases and exerts pressure on the walls of the tyre. Hence, after a certain threshold, the tyre bursts.
What are the applications of Gay-Lussac's law?
Gay-Lussac published his experimental results in c. 1808, which showed the direct relationship between the pressure and the temperature of a fixed amount of gas at constant volume. Some real-life applications of the law are as follows: The pressure cooker is a sealed utensil for cooking food under steam pressure.
What is Gay Lussac law of thermodynamics?
Gay Lussac Law of thermodynamics states that when the volume of a gas is held constant, pressure and temperature are directly proportional to each other. In layman when we heat the gas, its pressure will increase.
How can Gay-Lussac's law be verified?
The above diagram is a typical experimental setup required for verification of Gay-Lussac's law. When the air inside the chamber is heated with a heating source (electric heater is used in the diagram) via water, the temperature of the air increases i.e. the kinetic energy associated with the molecules of the air increases.

I am a mechanical engineer by profession. Just because of my love for fundamental physics, I switched my career, and therefore I did my postgraduate degree in physics. Right now I am a loner (as ever) and a Physics blogger too. My sole future goal is to do a Ph.D. in theoretical physics, especially in the field of cosmology.
What is Gay-Lussac's law?
Physical Chemistry. Gay-Lussac's law is also known as pressure law or Amontons's law. The law correlates how the pressure of a gas increases with an increase in temperature. This law is named after French chemist Joseph Louis Gay-Lussac. He formulated this relationship in 1808.
What is the difference between Gay-Lussac's law and Charles's law?
Gay-Lussac's law is similar to Charles's law, the only difference is the “volume” term in Charles's law is interchanged by the “pressure” term in Gay-Lussac's law. Table of Contents. 1 Statement. 2 Explanation. 3 Graphical Representation. 4 Limitations of Gay-Lussac's law. 5 Real World Applications of Gay-Lussac's Law.
Is Gay-Lussac's law applicable to gases?
The law is only applicable to ideal gases. Gay-Lussac's law holds good for real gases at high temperatures and/or low pressure. The ratio of the pressure to temperature deviated at high pressures. The ratio decreases with increasing the pressure.
What is Gay-Lussac's law?
What is Gay-Lussac’s Law? Gay-Lussac’s law is a gas law which states that the pressure exerted by a gas (of a given mass and kept at a constant volume) varies directly with the absolute temperature of the gas. In other words, the pressure exerted by a gas is proportional to the temperature of the gas when the mass is fixed and ...
What does the gas law mean?
The meaning of this gas law is that it illustrates that rising a gas’s temperature induces a relative increase in its pressure (assuming that the volume does not change). Likewise, reducing the temperature allows the strain to decrease proportionally.

What Is Gay-Lussac’s Law?
- It was observed that on increasing the temperature of a gas sample in a closed container, the pressure of the gas sample increases as well. This is because an increase in temperature causes an increase in kinetic energy of the gas sample, which results in the gas molecules striking the walls of the container with greater force, hence greater pressure. The French chemist Joseph Ga…
Formula and Derivation
- From Gay Lussac’s Law, we know that the pressure of a given mass of gas varies directly with the gas’s absolute temperature. Mathematically, \({\rm{P}} \propto {\rm{T}}\) Hence, the initial temperature and pressure of a gas varies as: \({{\rm{P}}_{\rm{1}}} \propto {{\rm{T}}_{\rm{1}}}\) \(\frac{{{{\rm{P}}_{\rm{1}}}}}{{{{\rm{T}}_{\rm{1}}}}} = {\rm{k}}……..\)Eqn (1) The final temperature …
