into typhoon.
EXPLAIN:
Activity 4 When tropical cyclone becomes stronger!
Directions: Identify the name of the cyclone as it pass through the stages of progression using
the descriptions below. Write your answer in the box.
Stages of Progression (not arrange in order)
Tropical Disturbance commonly exist in the tropical
trade winds at any one time and are
often accompanied by clouds and precipitation
Typhoon, Hurricane, or Cyclone. A pronounced rotation develops around the central core as
spiral rain bands rotate around the eye of the storm. The heaviest precipitation and strongest
winds are associated with the eye wall .
Tropical Depression
The winds blow stronger due to the greater convergence that causes
quicker decrease in the pressure. It increases in speed sustaining one -minute winds up to 38
mph at an elevation of 10 meters.
Tropical Storm The tropical storm receives an official name once
sustained winds reach
39mph in the closed circulation. The winds increase greatly and can take as little as a hal

What State of Matter Am I?
Good job! Matter is anything that has mass and volume. It is made up of tiny particles
that are moving all the time. These particles have spaces between them. From your previous
lesson, you had a better view of how these particles are arranged differently in each state of
matter, which are solid, liquid, and gas. Everything you have learned about the states of matter
is exactly what you need first to understand our new lesson for this week.

Activity 3: Serve it Hot or Cold?
Directions: Read the following scenarios carefully. Perhaps you have already encountered
almost the same situations at home. All you just need is a little curiosity, keen observation, and
the courage to ask questions. All of these will always help you learn something new.
C.
Scenario 2
Mang Kulas always drinks his hot coffee early in the morning.
One day he asked his grandson Jun-Jun to boil water for his coffee.
Jun-Jun obediently filled the kettle with one (1) cup of tap water
and mounted it on top of a cooking stove, and set it to medium heat.
After a while, Jun-Jun noticed that bubbles were formed, and some
vapor escaped out of the kettle beak. He decided that the water
inside is already boiling and turned off the cooking stove. He then
carefully poured the hot water into a clean cup.
To his surprise, the amount of water before and after boiling was
not the same. Jun-Jun wondered how it was possible. Nevertheless,
Jun-Jun continued preparing the coffee and served it to his
grandfather with a smile.
Based on the scenario you’ve just read, answer the following questions.
1. What did Jun-Jun observe when he decided that the water inside the kettle is boiling?

Scenario 3
The next day, Jun-Jun boiled water again for his grandfather’s coffee. Since his
grandfather was still on their farm, he covered the cup of hot water and set it aside. It took a
while for his grandfather to be home, and the cup of hot water had turned cold already.
Based on Scenario 3, answer the following questions.
1. Describe what must have been observed by Jun-Jun on the inside of the cup cover?

How did you find the activities? Was it fun? Were you able to share all your observations?
Were you able to draw all your observations? You just did a good job on doing your activities.
You are now ready to learn the reasons behind your observations.

What is it
Particles are always in motion based on the particle
model of the atom. The principle is presented at a
submicroscopic level of the activities that you just had. We
are focused on the particles of water that we refer to as
molecules that have kinetic energy that differs from one
another. Some molecules have higher kinetic energy than
others, making them move faster compared to the molecules
that have lower kinetic energy (see Figure 1). At room
temperature, some molecules of water have enough amount
of kinetic energy to break the attraction between the
molecules close to them. Once the attraction is broken, these
molecules will escape from the surface and will move into the
air. Thus, changing the phase from liquid to gas. This
process is what we call
evaporation. As evaporation takes place, the water molecules with lower Source: average ki
HYPERLINK
netic energy will not be able to escape and will be left in the liquid phase. Figure 1. Motion of
molecules during
Evaporation in sub-microscopic level.
It is important to take note that evaporation in an open container differs from evaporation
in a container that is covered. In an open container, once the molecules have enough energy to
break the attraction between neighboring molecules, they can freely escape into the air once they
transform into its gaseous phase. On the other hand, in a closed container, not all of the
molecules can escape into the air outside the container because some (in vapor form) may be
trapped on the cover.
In scenario 2, Jun-Jun observed that after boiling, the amount of water decreased. What
is the possible reason for this? As temperature increases, water molecules will gain more energy,
making them move faster. Water molecules will have the energy to break the attraction of nearby
molecules. These molecules will escape to its gaseous phase in the process of evaporation.
Evaporation and formation of gas can happen even below the surface of the liquid. That explains
the formation of bubbles that rise to the surface, and escape into the air seen as steam or vapor.
Jun-Jun may have seen both bubbles and steam and made him decide that the water is already
boiled.
The observation in the activities you had can be better explained in Figure 2. Recall your
lessons in math to read and understand the graph shown. The graph is composed of the y-axis
(vertical) where the temperature in 0C is
indicated, and the x-axis (horizontal), where
time is indicated. Drinking water (liquid) lies
between above 0oC and below 100 oC and is
represented by the letter A segment (dark).
When the temperature reaches 100 oC the
water (liquid) starts to boil. At this point,
evaporation takes place. Once the temperature
continues to increase, water molecules start to
become vapor (gas). On the other hand, at 100
oC, condensation may also take place when the
Figure 2. Change of Liquid to Gas
6
temperature of the water starts to decrease. So when boiled water in a cup is covered, some of
the vapor cannot escape and turns back into a liquid through the process of condensation
since the temperature is slowly starting to decrease.
In Scenario 3, Jun-Jun observed that droplets formed under cover of the cup. Where did
the droplets come from? Liquid water that changes into its gaseous phase is called water vapor.
The water vapor rises, and some molecules touch the cover of the cup. The cover is cooler than
the boiling water, so some of the heat energy of the vapor molecules are transferred into the
cover, in effect cooling the water vapor. If the particles lose enough energy, the attraction
between them can overcome their motion, which will make them attract with each other again,
making them go back to the liquid phase. The droplets under cover of the cup result from the
process called condensation (see Figure 3).
Not all of the water molecules change from liquid to gas. There is still water in their liquid
state that was left. Some of them might not have enough
energy to overcome the forces of attraction of the nearby
molecules. Moreover, some of the water molecules escape
and turn into vapor, some hit the surface of the liquid,
and if these molecules do not have enough energy to
Source: HYPERLINK
overcome the attraction, they will stay and remain in the

liquid state. The condensation process is exactly the

Condensation in sub -microscopic level.
reverse of the evaporation process.
Have you experienced waking up early in the
morning and observed fog around you? Or droplets of
water on a leaf early in the morning without rain the
other night? What about opening your packed lunch at
noon and seeing droplets of water under cover of the
container of your food? And of course, while drinking your cold drinks,
you see droplets of water outside the glass. These are examples of
condensation.

amount of water
2. Very small amount of water is left
3. With Cover: small of amount of water Without cover:
Very low amount of water
4. >It becomes a vapor
>It evaporates
5. There will be droplets under the cover

Activity 3. Serve it Hot or Cold?
Scenario 2 (Answers may vary)
1. Water is boiling bubbles and steam are both visible
2. The molecules move faster
3. The molecules gain high amount of energy breaking
the attractions from nearby molecules.
4. Amount of water will decreased because the water
will evaporate.
5. It goes into the air. It turns into is gaseous state.
Scenario 3 (Answers may vary)
1. There are droplets
Those are water in its gaseous state the returns back to its liquid state
3. Change from Liquid to Gas
When heated, water molecules become a vapor but since the cup is covered the
vapor in gaseous state is trapped and Goes back to its liquid the state again
Activity 4. What’s More
Molecules have high KE breaking
the attraction with other molecule.
Liquid changes to gas. Evaporation
takes place.

Molecules have high KE breaking the attraction
with other molecules. Liquid changes to gas.
However, some of the molecules are trapped
because of the cover. Evaporation takes place
but condensation will soon occur once the temp.
drops. Droplets will be seen under The cover.
