When a scuba diver descends into deeper waters, the pressure increases, causing the volume of air in their scuba tank to decrease according to Boyle's law. This is because as pressure increases, the volume of a gas decreases proportionally, illustrating Boyle's law in action.
when you are a diver the pressure in your lungs builds up. Without boyle's law your lungs could burst.
The bubbles exhaled by a scuba diver grow as they approach the surface of the ocean due to the decrease in pressure. As the diver ascends, the surrounding pressure decreases, causing the gas in the bubbles to expand. This expansion makes the bubbles appear larger as they rise to the surface.

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.
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.
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.
Action and reaction are always equal and opposite.
TRUE
There is absolutely no law against it. I would hate to see it happen though because 99% of scuba instructors are married.
The reaction force to Earth's gravity on the diver is the gravitational attraction that the diver exerts back on Earth. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, the Earth pulls the diver down, and the diver also pulls the Earth up with an equal force.
Boyle's Law, Charles's Law, and Archimedes principle are the main principles. Study those and that should get you started.
