Gas Laws And Equilibrium : Extended Response Task Scuba Diving

How is it possible for scuba divers to stay underwater for a long period of time? A man named Jacques Cousteau made that all possible. His invention of the aqualung made scuba diving possible, letting people explore the underwater world.

Also the amount of air molecules is greater at lower altitudes than at a high altitude. If an air molecule hits another air molecule even more air pressure happens. Air pressure can be felt while riding an express elevator to the top floor of a really tall building. Also it can be felt by diving all the way to the bottom of a swimming pool. The air pressure can also be formed when there is a lot of wind which causes the air molecules in the air to move around even faster and crash into each other even more.

7. What is the capacity of the air after it has descended back down to the sea level on the lee side of the mountains?

(#5) This is a benefit to society because it is so light whereas scuba diving equipment is hundreds of pounds.

Fleuss, adds to the first workable, independent diving ring that used compacted oxygen. In this model of shut circuit scuba, which is the precursor of present day shut circuit scuba units utilized by military jumpers, carbon dioxide is consumed by rope absorbed scathing potash, so that breathed out air can be re-inhaled . Despite the fact that profundities are constrained, the contraption takes into consideration moderately long base times, up to three hours. In 1880 Fleuss' contraption is utilized by the popular English jumper Alexander Lambert to enter an overwhelmed passage and seal a portal entryway; the portal is 60 ft down and 1000 ft once more into the

penetrated the water column up to 7 m during the day, and was generally low at night (Fig. 4).

As a result, it is a common practice to measure the volume of a gas by collecting said gas at the top of a container filled with water, with its opening facing downward in another container of water. This process is called collection of gas over water. The volume calculated from this practice may be used — in conjunction with two other factors (Pressure, Moles, or Temperature) — to determine another characteristic of a gas. This is able to occur due to the principles of the Ideal Gas Law. The Ideal Gas Law, PV=nRT, is derived from Boyle's Law, Charles Law, Avogadro's Law, and Gay-Lussac's Law,.

Jacques Cousteau invented this with Emile Gagnan. The design of the Aqua-Lung was finished in the early 1940s. The parts of the Aqua-Lung are the regulator, tanks, and a hose. For instance, in Paragraph 4, it states, “ Cousteau adapted Gagnan’s invention to create the ‘demand regulator,’ the defining component of the Aqua-Lung system. The regulator is the piece that fits into the diver’s mouth. The other essential parts were the tanks containing the air that were strapped to the diver’s back, as well as a hose to carry air from the tank to to the regulator.” Because of these features in the Aqua-Lung, divers are able to remain underwater for an hour or even more. Furthermore, the Aqua-Lung is different than the others in many ways. The Aqua-Lung allows divers to say underwater for much longer (one hour or more). Before, people could only remain underwater for a few minutes. In addition, in Paragraph 7, it states, “The Aqua-Lung automatically adjusted the pressure of the air in the tank to equalize air and water pressure.” The issue of water pressure is also addressed in the Aqua-Lung. The advantage of the Aqua-Lung allows the divers to stay underwater longer and adjust the pressure of the air in the

Water is around 800 times denser than air and much heavier. This is why only 5% of our oceans have been explored. The deepest part of the ocean is still unseen by humans. Everything in the deep ocean is under great pressure. At any depth in the ocean the weight of the water above pushes on any object below it. The deeper we go the more harmful to our bodies this can be. For every

With inaccurate information, critics say they are hard to control. According to livescience.com, one of the world's first deep-sea human submersibles, Alvin, was built in 1964. Alvin made more than 4,400 dives. According to the writers at livescience.com, WHOI's AUV descending as far as 19,700 feet (6,000 m) . According to the experts at livescience.com, it can travel to a depth of 14,800 feet (4,500 meters).

Robert Boyle, a philosopher and theologian, studied the properties of gases in the 17th century. He noticed that gases behave similarly to springs; when compressed or expanded, they tend to ‘spring’ back to their original volume. He published his findings in 1662 in a monograph entitled The Spring of the Air and Its Effects. You will make observations similar to those of Robert Boyle and learn about the relationship between the pressure and volume of an ideal gas.

The bends, also known as decompression sickness or caisson disease, is a condition which inflicts scuba divers and compression divers. It transpires as a result of nitrogen dissolving in the body when a diver stays under water for a certain amount of time. The solubility of gases increases as pressure increases, which is why the nitrogen dissolves in copious amounts when the diver is deep under water. As the diver rises to the top, the resulting decrease in pressure means the blood in their body can no longer hold all the dissolved nitrogen. This causes the dissolved nitrogen to be released as a gas. When the nitrogen is dissolved too suddenly, the diver experiences the bends. Symptoms often include headaches, itching, and joint pain. In serious

"The bends", or decompression sickness, is a condition that causes dissolved gasses to form bubbles inside of your body. The bubbles are made of nitrogen, and form in your body's tissue.These bubbles can travel any where in your body, which could result in death. Its caused by going deep down into the ocean and rising too quickly. To help prevent as many bubbles as divers can, they make their ascent rate time drawn out into sequences, example, 10 metres per minute, so about 33 feet per minute.

The purpose of this module is to investigate hydrostatic forces on a plane surface under partial and full submersion.
