“IT’S GETTING HOT IN HERE!”

2. What is Thermal Energy When any form of matter gets WARMER,
the kinetic energy of the
particles that make it up
increases.
This causes the object’s THERMAL energy to increase
Think of THERMAL energy as HEAT
An increase in thermal energy can lead to a
change of state
Ex: Solid to Liquid or Liquid to GAS

3. Thermal Energy
Thermal energy is measured by temperature – thermometers
Thermal (Heat) Energy can be caused by rubbing objects together

4. Thermal Energy Thermal energy is transferred (moves) in three ways
Conduction
Convection
Radiation

5. CONDUCTION The transfer of heat between objects that are touching
The stove
heats the pan
by conduction.
The handle will
also warm due
to conduction.

6. CONVECTION The transfer of heat by a moving liquid or gas
through ocean currents
is an example of
CONVECTION

7. RADIATION The transfer of heat by electromagnetic waves
ALL OBJECTS that emit light
give off thermal energy
in the form of radiation
