Energy Transfer

How does energy from the Sun reach the Earth?

• conduction

• convection

• radiation

• insulation

Rae'Dionce is sitting directly in front of a fire. She can feel the heat of the blaze warming her skin. What kind of heat transfer is taking place?

• conduction

• convection

• radiation

• precipitation

A material that does not conduct thermal energy easily is a(n)

• conductor

• metal

• radiator

• insulator

Which situation best represents conduction?

• the sun catching evaporation

• a pot of rapidly boiling water

• plastic melting on top of a hot burner

• hot gasses rising from a fire

Camels and gila monsters are common desert animals. A camel stores fat in its hump and a gila monster stores fat in its tail. These fat stores are primarily used for—

• storing water.

• energy when food is scarce.

• movement.

• attracting the attention of other animals.

Kayla has a wooden rod, a steel rod, and a glass rod. How could she compare the materials to find out which transfers thermal energy best?

• Submerge each rod in ice water to find out which loses the most heat.

• Place the three rods in a freezer to find out which becomes the coldest.

• Place one end of each rod in very hot water to find out which becomes hot the fastest.

• Place the rods on a table in a warm room and find out which feels warmest after a period of time.

Which best explains why a bowl becomes warm after holding hot soup?

• The heat is radiated from the soup to the bowl.

• The heat is returned to the bowl once the soup is cooled.

• The heat moves through convection from the soup to the bowl.

• The heat moves through conduction from the soup to the bowl.
