When one wants to set a time for relaxation and to be away from the seemingly routine life of the workplace then what better way to spend it with than a recreational activity such as scuba diving. There is no doubt that this underwater sport has truly captured the attention of the many thrill-seeker individuals who want to experience fun-filled experience that will be worth their time and money.

Scuba diving has continuously awed people like the first timers, experts, and professionals hence more and more have wanted to try this underwater sport. Both men and women, young and old, have trooped to the different scuba diving certification centers so they can get the most recent skills training. With the increasing emphasis on safety procedures in scuba diving, students are not only taught on the basic skills in the use and care of scuba equipment but the physics of diving as well.

Among the relevant lessons in understanding the physics of diving, the importance of leaning the gas that divers breathe while underwater is of paramount importance. Therefore it is only but essential that scuba diver wannabes must know the reason behind the relationship of pressure and gas underwater. For this reason, knowing and understanding about Charles’ law is just as necessary.

Charles’ law or what is also popularly known as the Charles’ gas law was named after the famous French scientist Jacques Charles. The law explains the relationship between the temperature and volume of any given gas granting they are both in constant pressure. This means that as the temperature, which is in Kelvin increases, the volume of that certain gas also increases hence the two have a direct proportional relationship given that the pressure and the volume of the gas are fixed. Understanding all this does not aim to make a diver to be an excellent physicist in the future but importantly help the diver appreciate the value of physics in diving like the Charles’ law of gas. Knowing this will also make the diver give importance on the utility of the scuba diving equipment more specifically the gas tank.


Even before scuba diving became one such popular sport and recreational activity in worldwide proportion Charles’ law has already been exploited in many scientific studies with the aim to improve human lives. The importance of the theories operating behind Charles’ law is mostly manifested in the art and science of scuba diving. Any scuba diving activity will never progress if the scuba divers are not familiar and have not mastered the famous Charles’ law. This is to make sure that divers have fully understood the scientific relationship of a certain gas with pressure, and temperature. This law will surely make divers implement the necessary safety precautionary measures to prevent the occurrence of underwater crisis or at least divers will know how to address if such is inevitable.

Simply put, when divers wish to push the limit and decided to go deeper, then divers should be aware that as they descend the pressure is increased hence the temperature and the volume of a certain gas in this case, the oxygen will definitely change since the pressure is no longer in its constant state. For this reason divers might have to need more oxygen than expected. So it is a must for divers to constantly check all the elements in Charles’ law such as the temperature, pressure, and the volume of the gas.

More than praising the inventor of scuba, if there is one person who also deserved accolades especially among scuba divers that would definitely be Jacques Charles for his valuable contribution of scientific discovery, which scuba divers have benefited in one point or the other. After all scuba diving is one scientific enterprise that phenomenally became one recreational activity.
