When a metal spoon is placed in a hot cup of tea, it soon becomes warm. Which mode of heat transfer is primarily responsible for this?
Conduction
Conduction is the mode of heat transfer responsible for a metal spoon warming up when placed in hot tea, as heat moves through direct contact within the metal.
Convection, radiation and insulation describe different heat transfer processes or the resistance to heat flow, not this direct-contact metal warming.
Hence, Conduction is the correct answer.
