How do you ascend slowly when diving?

SLOWLY KICK AND SWIM UP

Why is ascending slowly important when scuba diving relate your answer to Boyle’s Law?

Boyle’s law explains some of the most important safety rules in scuba diving. … Ascend Slowly – A diver’s body absorbs compressed nitrogen gas while he dives. As he ascends to a depth with less water pressure, this nitrogen gas expands according to Boyle’s Law.

What happens if you fart while scuba diving?

Why do scuba divers need to exhale air when they ascend to the surface of the water?

As the diver ascends, the pressure decreases. According to Boyle’s Law, this causes an increase in the volume of the lungs. The diver needs to exhale to adjust for the change in volume caused by the change in pressure.

Why beginning scuba divers are taught never to hold their breath while ascending from deep water?

When the diver surfaces- one of the most important rules is to be continuously breathing. Never hold your breath when ascending. This is due to the air in the lungs will start to expand because there is less pressure of the water exerted on the body. Holding your breath can cause catastrophic injury to divers lungs.

Why will a diver have difficulty when descending to deep ocean depths of the scuba tank contains only air?

Boyle’s Law

As a diver, Boyles law affects you every time you enter the water. Air spaces in the body are subjected to pressure and volume change, in direct proportion to your depth. … This part of the law becomes particularly important on deep dives; inhaled air will become denser the deeper one goes.

Why do divers dive backwards?

Just like using a diver down flag, diving back into the water is a standard safety technique. … Backward diving allows scuba divers to keep a hand on their gear while entering the water to avoid losing a mask or getting lines tangled.
