Exploring Thermal Energy Transfer Methods

What is the primary method of heat transfer demonstrated with the aluminum strip and nails?

• Conduction

• Radiation

• Evaporation

• Convection

Why do the nails fall off the aluminum strip in the order they do?

• Because the nails are of different sizes

• Because the strip is unevenly heated

• Because the wax melts uniformly

• Because thermal energy is transferred along the strip
