What has gas pressure?
Anything pressurised with gas - an auto tire for example, or a scuba diver's air tank.
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.
How scuba diver follows ideal gas equation?

When a scuba diver dives into water why are the gas bubbles they release always spherical?
The gas bubbles exhaled by a SCUBA diver are always spherical for two reasons: the gas molecules are pushing outward from the bubble in all directions with the same amount of force. In addition, the water outside the gas bubble is squeezing the bubble inward in all directions with the same amount of force.
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.
How would the pressure inside a scuba tank filled with gas change if the tank were heated?
The pressure will increase
Why is a scuba diver's air tank placed in a tub of water when being refilled?
Because compressing a gas increases its temperature. The increase in temperature increases the pressure further. By cooling the tank in water the tank can be filled with more air, it's also safer than having a very hot super high pressure tank at the end of the fill.
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
Does sugar really seize an car engine?
It seems that sugar in a gas tank has no effect whatsoever on a car engine. This myth was tested in Episode 15, "Scuba Diver, Car Capers" on the show Mythbusters (Discovery channel, Wed @9pm), along with other engine myths such as destroying an engine by adding bleach to the gas tank. http://dsc.discovery.com/fansites/mythbusters/episode/00to49/episode-07.html
What happens to the air from a SCUBA tank as you go down?
It passes thru the regulator where the surrounding pressure of the water regulates the pressure of the air in the line so that it is equal. This prevents any pressure differential that would make it hard to breathe.As for the air in the SCUBA cylinder, nothing happens to it as you go down. The pressure stays the same, etc. As to how breathing from a SCUBA cylinder works, there is an excellent answer under the question "How do you breathe underwater when you go scuba diving?"
What accounts for an increase in the temperature of a gas that is kept at constant volume?
Energy has been added as heat to the gas. Or pressure has been increased by adding more gas like a scuba tank.
Can scuba divers die under the water as their gas supply runs out?
Yes; if a diver runs out of breathing gas and they cannot either make it to the surface or share breathing gas with another diver nearby they will drown. However, this is actually quite rare in practice. Divers continually monitor their gas supplies, and always dive in teams so that in the event of an emergency (such as a blown O-ring), there is a buddy nearby to provide an alternative gas supply.
