Aburning piece of coal glows red on a lab table. a student wants to prevent the coal from transferring heat to him. he sets up a metal shield between himself and the coal to prevent convection. why will this not completely stop all of the heat transfer? the metal shield will heat up, and then heat the air on the student's side of the shield. the metal shield will cause more radiation to reach the student. the metal shield will not prevent heat transfer by conduction. the metal shield cannot block the flow of fluids.
