उत्तर

To Henry's law pressure of a gas is directly proportional to solubility. Scuba divers when coming towards surface the air pressure gradually decreases. This reduced pressure releases the dissolved gases present in blood and leads to the formation of bubbles of nitrogen in the blood. These blocks capillaries and creates a medical condition known as bends, which is painful and dangerous to live.
