Question

1. what type of thermal energy transfer occurs when the handle of a pan on the stove gets hot?

transmission
conduction
convection
radiation

Explanation:

• Conduction is the transfer of heat through direct contact between materials. In this case, the pan (a solid material) is in direct contact with the stove's heat source. The heat is transferred from the hot part of the pan (in contact with the stove) to the cooler handle through the solid metal of the pan.
• Transmission is not a recognized mode of thermal energy transfer in the context of heat transfer (the main modes are conduction, convection, and radiation).
• Convection involves the transfer of heat through the movement of fluids (liquids or gases). Since the pan handle is a solid and there is no fluid movement involved in heating the handle in this scenario, convection is not the answer.
• Radiation is the transfer of heat in the form of electromagnetic waves (like the heat from the sun). There is no indication of heat transfer via electromagnetic waves in the pan - handle heating scenario.

Answer:

conduction
