1.
Temperature is the same as thermal energy.
2.
Heat is the movement of thermal energy from a
hotter object to a cooler object.
3.
It takes a large amount of energy to significantly
change the temperature of an object with a low
specific heat.
The thermal energy of an object can never be
increased or decreased.

5.
Car engines create energy.
6.
Refrigerators cool food by moving thermal energy
from inside the refrigerator to the outside.
The sum of kinetic and potential energy of the particles
that make up a material.

The thermal energy from the warm
cup is moving to and heating up your
cool hands.

Liquids take longer to heat up and cool down because
they have a higher specific heat.
Large amounts of water have a very high specific heat, whereas the
cement around the pool has a low specific heat.

The heat from your soda moves
from the soda to the ice.
solids
direct contact
the fast moving, hot particles from
the fire transfer to the cool, slow
moving particles from the pan.
•
Insulator – a material through which thermal
energy does not flow easily. Insulators have a
high specific heat.
•Slows the transfer of heat.
•Examples: glass, wood, plastic, rubber, air, wool,
cork, straw, paper.
•This happens because
hot molecules are less
dense and rise whereas
cold molecules are
denser and sink
Convection currents
circulate the water in
Earth’s oceans and
other bodies of water.
