when your changing you might want to know...
when you are a diver the pressure in your lungs builds up. Without boyle's law your lungs could burst.
scuba diving.
Boyle's law deals with how gasses behave when the pressure changes. If you're a human, you are dependent on having some gasses in your body (Lungs, ears, sinuses...). And if you're a diver, you'll experience plenty of pressure changes. Knowing Boyle's law will prepare a diver for what he'll have to do to avoid injury.
as the bubbles get closer to the surface, there is less water pressure on them therefore allowing them to expand.
There are no legal requirements to scuba dive. In other words, anyone can scuba dive without breaking a law (assuming you are not doing an illegal underwater activity such as illegal fishing). However, if you are not certified, you will not be able to rent or buy equipment or get someone to fill your scuba cylinder.
There is absolutely no law against it. I would hate to see it happen though because 99% of scuba instructors are married.
Action and reaction are always equal and opposite.

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%
Boyle's Law, Charles's Law, and Archimedes principle are the main principles. Study those and that should get you started.
It depends upon your state law, but 100 feet would be a general answer.
