SCUBA essays

Scuba diving is a sport in which you can lose yourself to the beauty of the underwater world and escape gravity for a short time. You can wander among kelp forests or swim with sleek noble sharks. You can find a fortune in Spanish ducats or encounter a rare squid. Some may say that diving is "an extreme sport" and "it’s just for the wild hooligans.; Scuba diving is a safe and enjoyable hobby, which most people can experience if they have undergone proper training. Although there are many risks, most can be avoided when using proper technique and scuba diving ethics. Going below the water is vastly different from being above the water. While underwater there are forces and laws that dictate how your body will respond to being under so much pressure. Thefirst rule regarding the pressure water puts on the air spaces in your body is Boyles Law. It says that as the pressure increases on a given mass of gas the volume will decrease. This rule explains the popping sensation you feel when you go up in an airplane and the squeeze you feel as you go under water. Another law is Dalton’s law of Partial Pressure. It says that pressure of mixed gasses is equal to the pressure exerted by the individual gas. If a mixture of gas contains 5% carbon dioxide then it would account for 5% of the total pressure of the gas. Because of this law the concentration of harmful gasses must be less when you are under water, otherwise, you risk being poisoned by gas that would only occur at a higher concentration at sea level. The last major law that governs you while underwater is Henry’s Law. It simply states that you can dissolve more of a gas into a liquid at higher pressure and the opposite when you release some of the pressure. An example of this is found when you open a bottle of pop. The gas and pop are pressurized to carbonate it, and when you open the bottle bubble’s form, because the pressure isn’t…
