Question

ANY ONE CAN EXPLAIN ABOUT THE SCUBA DIVERS ?HOW IT WORK AT HIGH PRESSURE......AND WHAT IS THE FUNCTION OF HELIUM AND NITROGEN IN IT?PLZZ ONLY WHO CAN EXPLAIN...

Answer 1

Scuba divers have to suffer a lot at high pressure . As they move below the earth level ,pressure gradually increases. In there oxygen gas cylinders, some amount of nitrogen and helium is also added . It is because there is a threat of forming nitrogen bubbles when diver come towards surface . It may cause death of diver. So some amount of helium is added to cylinders ( about 1-2%) that prevent bubble formation inside our body system.
