Thermal Energy: Transfer & Transformation
undefined
Energy cannot be
created or
destroyed, it just
changes form or
moves between
objects.
There are many
different types of
energy.
Today we will be
focusing on
thermal energy
.
Thermal energy is a result of moving particles
inside of a substance.
Thermal energy can be transferred between
objects.
The transfer of thermal
energy between two
systems of different
temperatures is called
heat
.
There are 3 different
ways to transfer thermal
energy:
1.
Conduction
2.
Convection
3.
Radiation
Conduction is the
transfer of thermal
energy through a solid material
.
Heat is being conducted through
the stove burner to the frying pan.
Heat is being conducted through
the metal pipe to the hand.
Convection is the
transfer of heat
through liquids and gases by currents
.
Warm air rises, cool air falls. When warm air
cools, it falls, creating this cycle.
Traveling through liquid
Traveling through the air
(which is made up of gases)
Hot air rises, pushing
the hot air balloon
upward.
Radiation is
heat transfer by waves
.
When objects of different temperatures come
into contact with one another, the thermal
energy always travels from the
warmer
object
to the
cooler
object.
Hot
Cold
Thermal
Energy
Heat is always transferred, not coldness.
That’s why your finger feels cold when you
touch something cold.
The heat is leaving your finger and
transferring
into the cold object.
When you touch something hot, it burns
because the heat is being rapidly
transferred
to your finger.
When this energy transfer takes place, the
cooler object will warm up until the
temperatures are equal.
Is this an example of conduction,
convention, or radiation?
Explore thermal energy and its transfer mechanisms such as conduction, convection, and radiation. Learn how thermal energy moves between objects of different temperatures, and why heat is always transferred, not coldness. Enhance your knowledge on the fascinating world of thermal energy dynamics.

Heat is always transferred, not coldness. That s why your finger feels cold when you touch something cold. The heat is leaving your finger and transferring transferring into the cold object.
When you touch something hot, it burns because the heat is being rapidly transferred to your finger. transferred
When this energy transfer takes place, the cooler object will warm up until the temperatures are equal. Is this an example of conduction, convention, or radiation?
