2. States of Matter
“Boiling Point and Freezing Point”

3. SCIENTIFIC CONCEPT

4. Changes in the States of Matter:
• Heat is a form of energy which moves the particles in matter
• Changes in the states of matter can occur through heating or
cooling process. This is when the heat energy is absorbed or
released from the matter
• The changes in the states of matter which can occur during
the changes in heat includes:
i. Melting
ii. Freezing
iii. Boiling
iv. Condensation
v. Sublimation

5. • During cooling process, heat will be released
from matter and the state of the matter will
change from gas to liquid and finally to solid.

6. ENGAGE

7. What do you think?
It’s is heating here?

8. Is it FREEZING
here or BOILING?

10. PROCEDURE (S) :
1. Connect the sensor to an interface box linked
to the computer as shown in figure below.
2. Place the ice in the beaker and observed the
state of ice.
3. Place the temperature sensor in the ice.
4. Take reading for every 30 seconds of time
interval until it is boiled.

11. 6. Place Bunsen burner below the beaker for
heating the beaker. Click the start button.
Observe any transition process and the
temperature they start to change.
7. Record the data.
8. Plot graph temperature against times.
9. Cool the beaker to the room temperature.
Record the temperature and time taken for it to
cool.
10.Record the data.
11.Plot a graph of temperature against times.

18. DISCUSSION:
DISCUSSION
• The melting process is a process where the solid
phase changed to liquid phase under specific
pressure. The evaporation process is a process
where the liquid phase is changed to gas or
vapors phase.
• The substance used is water. The melting point of
water is 0 oC and temperature stay the same as
the melting process occurred. When water is
heated, the particles gain energy and move faster
as to move away their positions and begun to
vibrate around each other.

19. • The temperature during boiling process is
constant which 100 oC because the boiling
point of water is 100 oC. When a liquid is
heated, the particles gained energy and tends
to moved faster. Some particles in water,
which have enough energy to escape into air
to from vapor and this process is known as
evaporation.

20. • During solid phase, the water molecules are
vibrated around the point and not free to
move. It is expand, but, in a small value when
heat is supplied. This is due to the strong force
between the molecules. The energy in the
particles is low.

21. • During liquid phase, the water molecules
moved in random arrangement but still in
fairly stick together. The energy in the
molecules is moderate.
• During gas phase, the water molecules moved
in fast and randomly. The energy in the
particles in very high.

22. • During the cooling process, the
particles loss of energy and they came
closer together. As they collide, they
will stick together to form droplets
forming a liquid. During this process,
energy in particles is loss due to less
energy is needed as they are cooling.

26. A steam turbine is a
device that
extracts thermal energy
from pressurized steam
and uses it to
do mechanical work on
a rotating output shaft.
The turbine
generates rotary
motion, it is
particularly suited to
A rotor of a modern steam turbine, used
be used to drive in a power plant
an electrical generator.
