CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Boyle’s Law is also important to divers because it means that if a diver takes a lung-ful of air while he is underwater, that air will expand in his lungs as he rises to the surface. If he holds his breath, or ascends too rapidly (like a cork) the expanding air can rupture his lungs.

Detailed explanation-2: -You either have to swim for 200m using any style, and in any time frame or snorkel swim for 300m. You will also need to tread water or float for 10 minutes. It’s important to know that some medical conditions don’t go very well with scuba diving.

Detailed explanation-3: -Prolonged and high pressure diving may lead to various physiological changes including significant alterations of autonomic nervous system (ANS) activity that may be associated with altered physical performance, decompression sickness, or central nervous system oxygen toxicity.

Detailed explanation-4: -As a diver descends into deeper water, the pressure there increases the amount of gas that enters the tissues of the body. Oxygen is used by cells to generate energy by converting sugar to ATP. So the excess oxygen is partly used up and converted to carbon dioxide which is lost by breathing out.
