Thermal Energy Review

A barefoot student steps on a hot concrete surface. Most of the heat transferred to the student’s skin by this contact is by the process of—

• convection
• conduction
• vaporization
• radiation

The diagram to the right shows a solid iron bar that is being heated in a flame. The primary method of heat transfer in the solid iron bar is—

• convection
• conduction
• absorption
• radiation

A student opens the top window and the bottom window in a hot room. What statement best describes the heat transfer occurring in the room?

• conduction
• radiation
• convection
• evaporation

what is conduction?

• direct touch
• air or liquids
• heat waves/ light waves
• drinking hot coffee
