Charles Law is an Ideal Gas Law that establishes a relation between volume and temperature at constant pressure. In other words, according to Charles’s law definition; the volume of a gas increases with an increase in temperature at constant pressure and vice versa. Jaques Charles’s law is also known as the Law Of Volumes. In spite of the fact that Charles Law was discovered in the late 1700s, we can see applications of Charles law in our day to day life.
This phenomenon was demonstrated by French Scientist, Inventor, and Mathematician Jacques Charles who first proposed this law in his unpublished work in the 1780s.
Top 6 Applications Of Charles Law
If you think, you can’t relate to Charles Law examples in real life. Well, here is your chance to think again…!!!
- Hot Air Balloon
- Bursting Of A Deodorant
- Bakery Products
- Turkey Pop Up Timer
- Opening Of A Soda Can
- Helium Balloon On Cold Day
Hot Air Balloon
People often ask questions like – how do hot air balloons fly? Or how do hot air balloons work? Any guesses!!! Of course, whatever you are thinking it’s correct. The answers to all these questions lie in the vicinity of Charles Law.
In fact, if I talk about the history of hot air ballooning, Charles law and hot air balloons are somehow related. In other words, Jacques Charles himself was one of the famous hot-air balloonists.
He was notably one of the few people who flew the world’s first hydrogen balloon flight. The principle behind the working of a hot air balloon is quite simple.
Parts of a hot air balloon basically consist of an Envelope that stores heated air, Burner, and a Basket or Gondola to carry passengers.
When the fuel source is ignited, the air contained inside the envelope gets heated up. Charles’s Law states that with an increase in temperature of the air, the volume of the air will also increase.
Therefore, as a result, the density of air contained in an envelope becomes lighter than the density of the outside atmosphere. Hence, due to buoyant force, a hot air balloon flies high; up in the sky.
Bursting Of A Deodorant Bottle
The next one in the list of Top 6 Applications Of Charles Law is Bursting of a deodorant bottle. Well, as of today’s world, we all are well aware of the fact that what are deodorants. And why they are being used?
I also wonder how many of us get a chance to read the instruction written as a warning sign such as a ” pressurized container, protect it from sunlight. Do not expose to temperature exceeding 50°C”.

Ever thought why? Well yes, you guess is right. It’s because of Charle’s Law. According to Charles law definition; under high temperatures, the gas molecules inside the deodorant bottle expands. Therefore, leads to the bursting of the deodorant bottle…!!!
Well, Yes. One of the delicious Charles law examples in real life is a bakery product. I mean, if you love bakery products like bread and cakes, you can thank Jacques Charles.
Charles Law application in real life can be seen in our kitchen too. In order to make bread and cakes soft and spongy, yeast is used for fermentation.

Yeast produces carbon dioxide gas. When bread and cakes are baked at high temperatures; with an increase in temperature, carbon dioxide gas expands.
As a result of this expansion, our bread and cakes become deliciously spongy and fluffy in appearance and ready to serve.
Turkey Pop Up Timer
As I said, there is numerous application of Charles law in our kitchen too. Working of Turkey Pop Up Timer is based on Charles Law Of Thermodynamics.
As Charles’s Law states that a gas tends to expand when heated”, the same phenomenon works for Pop Up Turkey Thermometer. The turkey thermometer is placed inside the turkey.

As the turkey cooks, the gas inside the thermometer expands with an increase in temperature. Therefore, the turkey thermometer pop up; indicating that the turkey is cooked and ready to serve.
Opening Of A Soda Can
The next one in the list of Top 6 applications of Charles law is opening a soda can. I mean, have you ever wondered that when you open a chilled soda can, you hardly see any bubbles.
On the contrary, when you open a warm enough soda can, bubbles spill out of the drink. Any idea why? Yup, you are right. It happens because of the Charles Law Of Thermodynamics.
According to Charles’s law definition, in a chilled soda can, due to low temperature, there is a decrease in the volume. That’s why you hardly see any bubble coming out of the soda can.
On the other hand, in a warmer soda can, due to the high temperature, there is an increase in the volume. That’s why bubbles spill out of the drink.
Helium Ballon On Cold Day
The very last one in the list of Top 6 Charles law application in real life is the shrinking of a helium balloon on a colder day. Well, everyone is quite aware of what is helium balloon?
We all remember that during our childhood days when we step outside our home with a helium balloon on the chilly days (winter season of course).
The balloon will shrink a bit due to the degree of coldness or decrease in temperature. It happens because of Charles’s gas Law.
According to Charles law definition; when the temperature decreases so do the volume of helium gas inside a balloon. On the other hand, when the same balloon is brought back to a worm room, it regains its original shape.
