Morgan’s Proof of Review

• Heat & Energy

Heat

•Radiation•Conduction•Convection

Radiation

• The transfer of heat energy by electromagnetic waves.

• The suns heat gets to earth by electromagnetic waves.

• Heat from a fire is another example of radiation.

• Heat from a pellet stove is also an example of radiation.

Convection

• The transfer of heat energy within liquids and gasses by hotter molecules rising and cooler molecules falling down.

• Convection is the warm water vapor that rises into the air during evaporation.

• The balloon experiment did in class.

Conduction

• The transfer of heat energy within a solid object or between two (or more) objects that are touching.

• Conduction is a hand getting burned by touching a hot pan on a stove.
