How does thermal energy transfer occur through conduction?

• Heat is transferred through direct contact between objects.

• Heat is transferred through radiation.

• Heat is transferred through convection.

• Heat is transferred through electromagnetic waves.

Explain the process of thermal energy transfer through convection.

• Convection is the process of thermal energy transfer through radiation.

• Convection is the process of thermal energy transfer through the movement of fluids.

• Convection is the process of thermal energy transfer through conduction.

• Convection is the process of thermal energy transfer through the movement of solids.

• It remains constant.

• It disappears.

• It doubles.

Nash puts his cold Coke Slurpee on to the metal roof of his mom's car. Describe the heat transfer that takes place.

• Heat is transferred from the car's roof into the Slurpee and increases the temperature of the Slurpee.

• Heat is transferred from the Slurpee into the roof and increases the temperature of the roof.

• The Slurpee stays the same temperature until it is completely gone.

• The roof doesn't change temperature due to the fact that it sits in the sun all day.

What type of heat transfer is happening at "A"

• conduction

• convection

• radiation
