This document discusses heat transfer and thermal energy. It defines heat as a form of energy produced from the movement of thermal energy. Thermal energy is the energy possessed by objects due to the movement of particles. Heat transfer can occur through conduction, convection, or radiation. Conduction involves direct contact between objects, convection involves the circulation of particles in fluids, and radiation emits electromagnetic waves. Metals are good conductors of heat while insulators are poor conductors. A thermometer is used to measure the temperature or degree of hotness and coldness of objects.

HEATARCHIE A. DURAN

2. Have you
experienced
heat?

3. Thermal Energy
a form of energy
possess by all objects
it is due to the movement
of particles making up an
object

4. what is heat???
also a form of energy like
thermal energy.
produced as thermal
energy moves.

5. heat energy production starts
when thermal energy starts
transferring.
heat energy production stops
when thermal energy stops
transferring.

6. Thermometer
an instrument used to
measure the degree of
hotness or coldness of an
object.
measures temperature.

13. Until when do you
think will heat
transfer continue to
take place between

14. How does heat
transfer?
Conduction
Convection
Radiation

15. Conduction
takes place between
objects that are in
contact with each other.
transfer of heat by
vibration.

16. The energy from the object of
higher temperature is transferred to
the other object through their
particles that are close or in contact
with each other.

17. Then the particles receiving
the energy will also transfer
the energy to other places
within the object through
their neighboring particles.

18. During this process, only
the energy moves, not the
matter itself.

20. Example
Think of a metal spoon put
in a bowl of a hot
champorado that you were
about to eat when you
suddenly remembered that

21. heat
conductivity
different materials transfer heat
faster than the other.
good conductors-fast transfer
insulators-slow or even prevent
transfer

23. Generally, metals are
good conductors of
heat.

25. Convection
transfer of heat by the
movement of particles.
happens only in fluids
(liquids and gases)

31. Radiation
refers to the emission of
electromagnetic waves
no particles are involved
can take place even in
vacuum.

32. All objects emit and
absorb radiation, known
as thermal or infrared
radiation.

33. The hotter an object is,
the more infrared
radiation it emits.
