How to use CalculatorHut’s Boyle’s Law calculator?īoyle’s law is widely used in many physics calculations. Thus the discovery of Boyle’s law leads a path to great inventions which are now intertwined to the survival of human life. If not, it leads to the formation of tiny bubbles in his tissues and blood and causes decompression sickness. Hence a diver has to ascend slow enough so that his body gets time to eliminate the expanding nitrogen gas. When he ascends to a depth which has lesser water pressure, nitrogen gas absorbed by him expands. Ascend Slowly – During Scuba, diver's body underwater tends to absorb nitrogen gas in compressed form.This phenomenon can lead to an injury to the diver's lungs causing pulmonary barotrauma. Breath should not be held underwater – In scuba, when a diver holds his breath underwater during ascending to an area having lesser water pressure, his lungs will expand trapping the air according to Boyle's Law.He will have to equalize thus created pressure in his ears to avoid ear pain which can lead to an ear injury called ear barotrauma.īesides, the above the rules to have safe diving are derived from Boyle’s law calculations. Descent: Inversely when a diver descends, the pressure of water surrounding him increases, and the air in his ears gets compressed.If he does not release excess air from BCD, he will lose control over his buoyancy because of the air expansion. This is because, during the process of ascend, the pressure of water surrounding him decreases, and the air in his BCD expands. Ascent: When a diver ascends, he will have to release the excess of air from his buoyancy control device (BCD).The techniques which scuba divers use to ascend descend and breathe under waters holds as good examples of applications of Boyle’s law. When we say that pressure inside the lungs is high, it is even higher than outside atmospheric pressure and thus we can move the air out from our lungs using exhalation.Īnother example where we are applying Boyle’s law is in “Scuba Diving”. Thus reducing the volume of the lungs and increasing the pressure inside them. Similarly, when we breathe out, that is during exhalation, the respiratory muscles contract and decreasing the size of our chest.When we breathe in air, we are drawing the air into lungs and contracting the respiratory muscle and thus increasing the volume of the chest which again decreases the pressure in our chest.Do you know!!! There are plenty of examples of Boyle’s law in the things that we do daily.įor example, breathing! Yes, the way we breathe or take the air into our lungs is a clear picture of Boyle’s law.
