correct data, then
solve and check it using Boyle’s law
equation: P₁V₁=P₂V₂
Problem to be solved and to be checked using Boyle’s Law
equation:
P₂=P₁V₁/V₂
In a J-shaped tube filled with mercury, initially, mercury
levels in both limbs are the same. The initial volume of the 760mmHg(.5L)
0.30L
trapped gas in the closed end is 0.50 L. The volume of the gas
decreases to 0.30 L after the addition of mercury from the open

end of the tube. Take note that the opened end of the tube is
MmHg
subjected to the atmosphere; thus, the initial pressure is equal
to atmospheric pressure (1 atm = 760 mmHg). What will be the
final pressure after the changes of the volume happened?

Activity 3: Boyle’s Law in Scuba Diving
Objective:
At the end of this activity, you should be able to appreciate
Boyle’s law and cite its practical applications in your daily life.
Materials: Picture of a scuba diver
Directions: Rearrange the jumbled letters inside the
parenthesis, then fill in each blank with a correct answer. Relate

each statement to scuba diving activities.
Diving into deep water is another application of (1)
___________ (s’leByo) law. As the diver moves down to the
bottom of the water, the (2) ____________ (respseru)
increases. Increasing pressure leads to a decrease in (3)
_________ (lovemu), and the diver’s blood begins to absorb
the nitrogen gas. The opposite happens when the diver starts
to rise again, and the nitrogen gas molecules begin to expand
and return to its volume. If the diver makes a slow rise, the
nitrogen gas (4) _____________ (lesmolecu) expand and
return to normal without problems, but if it rises quickly, the
diver’s blood turns into foam and the same mess that occurs in
the soda bottles causes the diver to bend and feel strong pain.
In the worst case, this sudden drop in body pressure can
instantly terminate the diver’s (5) ___________ (ifel).
Closure:
When a scuba diver dives beneath the water
surface due to the hydrostatic pressure on divers, the air inside
their lungs contract. As a diver approaches the surface, the air
inside their lungs expand since the pressure (6) ____________

5.In the case of soda bottles or cans, all of us apply Boyle’s
Law but unintentionally. Note that when you open the bottle of
soda quickly, the gas rushes from everywhere
in the
form of foam, causing a mess. So, what is the cause of this
mess?
A. This mess occurs because the soda bottle is pumped by
passing the water on carbon dioxide.
B. This mess occurs because the soda is pumped into the soda
bottle by passing carbon dioxide into the water.
C.When you open the bottle, you are actually reducing the
pressure on the gas, and the volume of the gas expands.
D.When you open the bottle, you are actually increasing the
pressure on the gas, and the volume of the gas expands.
