Estimate the volume of your kitchen oven and guess how many Watts it takes to pre-heat the air in your oven from 22 °C (72° F) to 221 °C (~430° F)? If the amount of steel that is heated in the inside of the oven totals 3 kg, how many Watts additionally does it take to pre-heat that? Time your oven to preheat and estimate the average Q needed.

Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.
