Paper Title:
The transfer of energy as heat can be controlled.
Energy moves heat in 3 ways.
1. Conduction
2. Convection
3. Radiation
What is conduction?
Conduction is the process by which
energy moves from a warmer object to a
cooler object when the objects are
touching.
Conduction Example a:
Energy moves from a warmer object to cooler object when the objects are
touching.
Conduction Example b:
Energy moves from a warmer object to cooler object when the objects are
touching.
Conduction Example c:
Energy moves from a warmer object to cooler object when the objects are
touching.
What is convection?
Convection is a process by which energy is
transferred in gases and liquids; occurs
when a warmer, less dense area of gas or
liquid is pushed up by cooler, more dense
area of the gas or liquid.
Convection
Large bodies of water, such as Lake Michigan,
influence the temperature of the land near by.
During the spring and early summer, the lake is
cool and warms more slowly than land. The air
above the land gets warmer than the air over the
water. The warmer air is pushed above the land is
less dense than the cooler air above the water.
The cooler, denser air moves onshore and pushed
the warmer air up. The result is a cooling breeze
from the lake.
Convection Example a:
Convection
2. As the air cools, it
becomes more dense
and starts to sink.
1. Warmer, less dense
air is pushed up by
cooler, denser air.
Where is the cycle of
air more dense? Less
dense?
3. Sinking air moves
under warmer air
pushing it upward.
The warm ground transfers energy
to the air by conduction.
Convection Example b:
Convection Example c:
What is radiation?
Radiation is the transfer of energy across
distances in the form of electromagnetic
waves.
Radiation Example a:
How does radiation transfer energy?
-When electromagnetic waves strike an object, they transfer
energy to the object.
Radiation Example b:

Radiation
