3. Review about the Kinetic molecular theory (KMT) of
Gases
1. A gas consists of very small
particles, each of which has a
mass.
2. The distances separating gas
particles are relatively large.
3. Gas particles are in constant,
rapid, and random motion.
4. Collisions of gas particles with
each other or with the walls of the container are
perfectly elastic.
5. The average kinetic energy of gas particles depends
only on the temperature of the gas. Gases have higher
kinetic energy at a higher temperature and lower kinetic
energy at a lower temperature.
6. Gas particles exert a force on one another. In other
words, the attractive forces between gas particles are so
weak that the model assumes them to be zero.
4. Unlocking of terms:
-pressure of the gas is the force it exerts on the wall of
its container.
-volume is the amount of space that a substance or
object occupies.

How these things works?
Ans: (Possible Answer)
Lungs- When you breathe, your diaphragm moves
downward, increasing the volume of the lungs. This
causes the pressure inside the lungs to be less than the
outside pressure so air rushes in.
Plunger- When the plunger is drawn back, the
increase in volume inside the syringe creates a law
pressure (vacuum) that draws the liquid from the vial into
the syringe
Aerosols- such as spray paints, pushing spray
button creates an opening between the inside of the can
and the air outside.
gas flows out of can and this movement propels or forces
the paint out of the can.
Activity I. Divide the class into 5 groups and each group

The relationship between the volume of a given quantity
of a gas and its pressure is expressed by Boyle’s Law.
This law states that the volume occupied by a gas is
inversely proportional to the pressure if the temperature
remains constant.
Meaning, at constant temperature, if there is an increase
in pressure, volume will
decrease. If there is an increase in volume, pressure will
also decrease. Boyle’s law was first stated by Robert
Boyle in 16th century.
Divide the class into four groups. Ask each group to
perform Activity 2 pp.362-365 Science Learner’s Material

Groups 1 and 2: Present Table 5 (Observation on Volume
Changes)
-What happens to the volume of the syringe as the set of
weight is added on top of it?
Ans: decreases
-What happens to the pressure on the syringe when the
set of weights is added?
Ans: increases
Group 3 and 4: Present and describe the graph showing
the relationship of volume and pressure at constant
temperature.
Ans: the graph shows that at constant temperature, if
there is an increase in pressure, volume will
decrease. If there is an increase in volume, pressure will
also decrease.

How Boyle’s Law applies to Scuba Diving?
Ans: Boyle's Law applies in scuba diving because it
means that if a diver takes a lung- ful of air while he is
underwater, that air will expand in his lungs as he
rises to the surface. If he holds his breath, or ascends
too rapidly (like a cork) the expanding air can rupture his
lungs.
What is the relationship between pressure and volume of
gasses at constant temperature?
Ans: if there is an increase in pressure, volume will
decrease.
What is Boyle’s Law?
Ans: Boyle’s Law state that the volume occupied by a
gas is inversely proportional to the pressure if the
temperature remains constant.

Materials
25 ml syringe
Set of weights
Ruler
Glue stick
5” by 3” illustration board
6” by 4” by 0.25” wood
candle or glue gun
match (if you opted to use candle)
Activity 2 Procedure:
1. Fill the syringe with air by pulling the plunger. See to it that the volume reading is at approximately 25.0
mL.
2. Seal the opening of the syringe with the melted glue stick.
3. Bore a hole that is very close to the size of the opening of the syringe in a 6” by 4” flat wood. Screw the
wood on a stable object. Insert in an upright position the sealed part of the syringe in the hole of the
wood, be sure it is sturdy.
4. Paste a 5” by 3” illustration board at the end of the plunger. This will serve as the holder of the weights.
You have just prepared a Boyle’s Law Apparatus.
5. Carefully place a 200-gram weight on the holder and get the volume reading.
6. Place one at a time different weights to the plunger. If you do not have set of weights you may use books
of the same kind. Be sure to get the mass of each book.
7. Record the mass and volume reading using Table 5.
8. Graph your data.
