This ppt is for those seek more understanding and more information about the topic.

2. Describe heat energy and its
functions.
Explain the relationship between
temperature and heat.
Define conduction, convection, and
radiation.

6.  is a form of
energy that refers
to the thermal
energy that is “in
transit” or in the
process of being
transferred.

7. It indicates the degree of hotness or
coldness of a body or a place.
It is the quantity that tells how warm or
cold an object is with respect to some
standards.

8. It is the
device used
to measure
the
temperature

13. Conduction occurs
when energy is
passed directly
from one item to
another by
touching the two
objects.

14. Metals are excellent
conductors of heat energy.
Wood or plastics are not.
These “bad” conductors are
called insulators.
 That’s why a pan is
usually made of metal while
the handle is made of a
strong plastic.

15. Convection is the
movement of gases
or liquids from a
cooler spot to a
warmer spot.

17. The sun’s light and heat
cannot reach earth by
conduction or convection
because space is almost
completely empty.
Transfer of energy from
the sun.

18. Takes place
even in the
absence of
material.

24. •Heat always passes from a
until all objects are the same temperature.
•Conduction is how heat travels between objects that
are touching.
•Conduction travels fastest through solids, but liquids
and gases can also conduct heat.
•Some materials, like metal, can conduct heat very
quickly, while other materials (like plastic or wood)
conduct heat very slowly.

25. •Convection is how heat travels through fluids – liquids
and gases. Hot fluids rise up, while cold fluids sink
down.
•Radiation is how heat travels through empty space.
Radiation does NOT require molecules to travel
through. Any time you can feel heat without touching
it, you are experiencing radiation.

26. Is the ability of a
material to conduct
heat

28. 1. Hot coffee is stirred with a spoon. Why?
Answer: CONDUCTION. Because the heat transfers when the objects
are in contact.
2. Near the ceiling of a room the air is warmer. Why
Answer: CONVECTION. Because heat travels through fluids – liquids
and gases
3. A chair is placed several feet from a fire in a fireplace. Why?
Answer: RADIATION. Because heat travels in rays or waves.
