Important Information about Boyle's Law

 Every scuba diver's life depends on a law discovered by Sir Robert Boyle in the 1700s. Boyle's Law
explains why when pressure is exerted on a gas the volume of the gas will decrease or when pressure is
reduced on a gas and the volume increases. The Law is explained by this mathematical equation:
P1*V1=P2*V2. Now, you might ask why this is important to a scuba diver? Well, the answer is that when a
scuba diver goes down underwater, his scuba equipment must provide air at a pressure equal to the water
pressure at the depth of a diver. If air did not adjust to the pressure of the ocean, our lungs would
not get enough oxygen. Now when that scuba diver starts to surface, the air will keep on expanding,
because of the pressure of the ocean decreasing. The air will expand and cause the lungs to expand too.
.The lungs will only expand though if the scuba diver holds his breath. This explains why one of the main
rules of scuba diving is to not hold your breath, for if we did, or lungs would burst.

 

Facts to Know

 -Boyle's Law Only works when the temperature of the
gasses remains constant
-Boyle's Law goes hand in hand with Charles' Law
-Charles' Law states that "The volume of the
gas is changed by temperature. As a gas heats
up it expands and becomes less dense. As a
gas cools it decreases in volume and becomes
more dense."
-Boyle's Law is an inverse variation
