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%
Gay-Lussac's gas law states that the pressure of a gas is directly proportional to its temperature, when volume and amount of gas are constant. In Scuba diving, this has implications for the compression and expansion of gases in scuba tanks as divers descend and ascend in the water. Understanding this relationship is important to prevent issues such as decompression sickness.
Boyle'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.

Which gas law best explains diving medical problems?
Henry's law is the gas law that best explains diving medical problems. It describes how gases dissolve in liquids, such as nitrogen dissolving in blood and tissues during scuba diving. This can lead to decompression sickness if the nitrogen is not properly eliminated from the body.
What type of gas builds in blood?
Nitrogen gas can build up in the blood during scuba diving due to the increased pressure at depth. This can lead to decompression sickness, also known as "the bends". Oxygen can also build up in the blood at high concentrations and lead to oxygen toxicity.
Scuba tanks have wh at noble gas in them?
Scuba tanks are typically filled with compressed air, which is a mixture of oxygen and nitrogen. However, some scuba tanks may also contain a noble gas such as helium as part of a special gas mix called trimix, which is used for deep dives to reduce the risk of nitrogen narcosis.
How is boyle's law used in technology?
Boyle's Law is used in various technological applications that involve gas behavior, such as in scuba diving equipment, pressure sensors, and pneumatic systems. Understanding how changes in pressure and volume relate to each other allows for the design and operation of efficient and safe devices that utilize gases.
Why is nitrogen added to scuba tanks?
Nitrogen is added to scuba tanks as part of the breathing gas mixture to dilute the higher oxygen content. This helps reduce the risk of oxygen toxicity at deeper depths while still providing enough oxygen for the diver. Oxygen toxicity can be dangerous for divers, so nitrogen is used to make the gas mixture safer for breathing.
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.
Why does a scuba diver need increased gas in the air tank?
Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
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 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 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 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.
What are the technologies involving gas laws?
Technologies involving gas laws include compressed air systems, fuel injection systems in vehicles, HVAC systems for regulating air flow, and scuba diving equipment for managing gas pressure underwater. These technologies utilize principles of gas laws such as Boyle's Law, Charles's Law, and the ideal gas law to control the behavior of gases in practical applications.
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.
Without this noble lightweight the Goodyear Company would never have gotten off the ground and scuba divers would really be hurting?
The Noble of gas of helium (He) allows for the Goodyear Blimp (an airship) to rise. Helium (heliox) mixtures also allow for deep scuba diving.
You want to convert a SCUBA tank for use as CNG tank?
the silly answer is you can store anything in a scuba tank that you can get in it!!. BUTthe serious answer is scuba tank were designed for compressed air and nothing else... using a scuba tank for natural gas is like driving around with a bomb in your car!!, the valves and collars of the bottles are not strong enough if there was a crash
Which gas law best explains diving medical problems?
