B. Establishing
Purpose for Anyone who can identify the properties of The characteristics and
the lesson the gas? properties of gases are
described fully in terms of four
parameters or measurable
properties. The volume,
pressure, temperature and
mass.
Exactly!
We have pressure which defined as the
forced applied per unit area, volume is the
amount of space occupied by gas, and
temperature measures the coldness and
hotness of a gas.
Yes, Ma’am.
Do yu still remember this lung model you
have learned before?
The balloon represents the
What does the balloon represents? diaphragm and lobes of lungs
showing the principles of
exhalation and inhalation.
As you exhale, the diaphragm contracts, it
results to a decrease in the lung volume,
increasing the pressure in the chest
activity. As you inhale, the lung cavity
expands, causing the pressure inside the
lung to decrease, and become lower than
the outside pressure.
That example has something to do in our
topic today. Our objectives for today is
you should be able to describe the
relationship between volume and pressure
at constant temperature of a gas, state

problems on Boyle’s law.

up its volume goes down as a volume of a

down.
Can someome share an example, on what

Who introduced the relationship between higher pressure, if you keep
volume and pressure? the amount of gas particles in

size of the container bigger so
Who is Robert Boyle? fewer collision will occur that
registers lower pressure.
The relationship between
volume and pressure was first
stated by Robert Boyle.
He is the person who
discovered that the volume of
a gas is inversely proportional
to its presure at constant
temperature.
What experiment he does to prove this?
He performed an experiment
wherein he trapped a fixed
amount of air in the J-tube, he
changed the pressure and
controlled the temperature and
then, he observed its effect to
the volume of the air inside the
J-tube. He found out that as
the pressure is increased, the
volume decrease. He finally
concluded that the volume of a
fixed amount of gas inversely
proportional to its pressure at
constant temperarure.
This can be expressed in an equation
