Why does heat travel from something
hot to something cold?
Temperatures are
attempting to be equal,
balanced.
Hot
Cold
Same temperature
What does the Law of Conservation
of Energy state?
Energy can not be created or
destroyed.
Which picture demonstrates the
energy transfer from radiant to
chemical to light?
A
B
RadiantChemicalLight
Do you want the handle to be a
good conductor or a good
insulator?
When grabbing a hot fry pan, we want
the handle to be made of a good
insulator. Insulators have low thermal
conductivity.
Which picture shows chemical
energy being transformed into
kinetic (mechanical) energy?
A
B
A car moving represents the
transformation of chemical
energy to kinetic (mechanical)
energy.

Which picture shows stored
potential energy?
A
B
A ball on a hill shows stored
potential energy.
