Okay, so Dalton's law basically boils down to the pressure exerted by a mixture of gases is equal to the sum of the pressures which would be exerted by the gases individually.
Why is this important to Scuba divers? Because gases at pressure is what keeps us alive. Remember, in my scuba cylinders I have air compressed to 3,000 PSI. And I want to know that when I take air (21% oxygen 79% nitrogen*) and compress it, that the components of air will compress evenly so that when I am at depth, and the pressures change, the air will still be the same ratio.
Again, why is this important to scuba divers? because knowing that allows me know know how much nitrogen that I've been sucking, which is key to avoiding decompression sickness (aka the bens). All my tables that tell me how long/deep my repetitive dives (2nd dive of the day, 3rd dive of the day, etc) are based on how much nitrogen are still in my system. This allows me to keep an excessive amount of nitrogen from entering my bloodstream, and potentially killing me (generally something I try to avoid)
* before I get anything from people about the composition of air, yes, I know the closer breakdowns are:
Nitrogen: 78%
Oxygen: 21%
Other: 1%

∙ 15y agoBoyle's law determines the volume of gas (s) and states " At a given temperature the volume of a given mass of gas will vary inversely with the absolute pressure"
It's application from a divers perspective is this.
The volume of gases are reduced when the pressure is increased..Diver descending.
The volume of gases is increased on the reduction of pressure...Diver a ascending.
Bubbles get smaller in size when pressure increases and they expand when pressure decreases.

∙ 10y agoby analyzing the experimental data it is clear that the relation of gay-lussacs law is proportional to the volume of the given substance. Therefore gay-lussacs law is related to scuba diving.

Scuba tanks have wh at noble gas in them?
Some advanced divers dive using gas mixtures including Helium.
Why is nitrogen added to scuba tanks?
The same reason every other gas in a scuba cylinder is compressed. If a cylinder is pressurized, then the gas in it is compressed by definition. If it is not pressurized, then there is obviously no gas in the cylinder to breath.
How does metallic bonds relate to a noble gas electronic configuration?
there is no relation between these two
Is oxygen gas also known for helium?
Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
What is the percentage of oxygen and helium in diving?
The percentage of oxygen in diving varies depending on the diving depth and the type of diving. For recreational diving, the typical oxygen concentration is around 21%. However, for technical diving, the oxygen concentration can be increased up to 100% to reduce the risk of nitrogen narcosis at greater depths. Helium is often used as a diluent gas in technical diving to reduce the amount of nitrogen in breathing mixtures at very deep depths. The percentage of helium varies typically between 0% and 90% depending on the dive plan and depth.
Is scuba diving when the tanks are floating on top of the water if not what type of diving is it when the tanks float on top?
Its not really scuba diving but its considered scuba diving. Also known as the hookah system. its when you have a gas powered motor pumping fresh air to the person or person's diving below, there can be up to four people diving off of one hookah system. the benefit of this system is that there is no decompression time and you can be underwater pretty much all day if someone fills the gas tank on the engine pumping air. but you are kinda tied down to something so i don't think its true scuba diving.

Do you have to go to college to scuba dive?
No, you do not have to go to college, but you do need specific training. They usually have this training at something like a YMCA or something similar. This training, while expensive, allows you to take multiple dives, lessons, and a test to get your diving certification card. This card allows you to dive, but you should never (I repeat, NEVER) go diving alone. This card allows you to get scuba gear and gas for scuba diving.
Is scuba diving safe during pregnancy?
NOT SAFE!! http://scuba-doc.com/prgdiv.htm
Is scuba diving a type of science?
The best answer is probably no. Safe scuba diving relies heavily on a knowledge of physics, gas laws and even physiology. Since it generally takes place in the ocean, it often involves marine biology. In that respect scuba is far more reliant on science than most other activities. Generally, though, scuba is a recreational activity for most divers and a vocation for others.
What is the difference between sub aqua diving and scuba diving?
Not necessarily. It just depends on what someone means. Scuba diving is only when you use a scuba tank or cylinder that a diver carries. Deep commercial divers will often get their breathing gas supplied to them through a long umbilical hose ... so they are attached and do not carry Self Contained equipment that they can swim with like a SCUBA (self contained underwater breathing apparatus) diver.
What is the scuba diving sports?
There are currently no professional sports that involve scuba diving.
What are the educational qualifications of deep sea diving?
"Deep" diving is diving farther than 120'. Though there are no educational qualifications per se, there are a number of certifications needed to do it safely. Certifications differ from agency to agency, but usually include: -Scuba diver -Advanced scuba diver, with deep dive training -Mixed gas diving -Multi-stage decompression diving -Diver rescue Specialized equipment includes: -Dry suit -Breathing gas mixtures such as trimix, heliox, etc (some use pure oxygen for decompression -Dive and decompression computers -Powerful underwater flashlights -More stuff I can't remember.
What are the technologies involving gas laws?
Some technologies involving gas laws include: -Hot Air balloons -Scuba diving equpiment -Airplanes -Welding -Neon and fluorescent lighting -Air bags -Making bread
What education and training is required to become a scuba diver?
The interesting thing about scuba diving, is legally, there are no licenses or certifications required. The problem arises, however, that while scuba is an extremely safe sport, some training is required to make it safe. And from a liability standpoint, dive shops, and dive resorts will not rent gear, or take people diving unless they can show a scuba license (or C-Card - certification card) from a recognized training agency.You can take classes locally or online that teach scuba diving, and upon graduation from the class, a certification card (which resembles a credit card) with your name, date certified, etc is given. That card will be required in most any location in order to dive.There are different levels of certification, Open Water Scuba Diver, Advanced Scuba Diver, Rescue Diver, Divemaster, Instructor, etc, and by taking additional classes, someone can gather more experience, education and certifications.Beyond recreational diving, there are courses for technical diving including deep, mixed gas, cave diving, etc, and there are also commercial dive courses covering everything from underwater welding, inspection, etc.
How can helium help us?
It is extremely light and non-flammable so ideal for balloons. It is an ideal carrier gas for Gas Chromatograhy for laboratories all over the world. At certain pressures when scuba diving it is used with oxygen to breathe.
Is scuba diving dangerous if you have a ventricular septal defect?
Scuba diving is dangerous even if you have nothing wrong. It is slightly more dangerous with this condition. it is best to be cleared medically before you scuba dive.
