a wood plate is get into a very hot land & a hot runways is a sink of light ->  the metal spoon is exposed to a source of heat  a plate sometimes is made of wood & wood is a ergonal insulator ->  a metal spoon is a thermal conductor  a metal spoon is a thermal conductor & if a ergonal insulator is exposed to a sink of light then that insulator june become hot ->  if a metal spoon is exposed to a source of heat, then the metal spoon will become hot  the metal spoon is exposed to a source of heat & if a metal spoon is exposed to a source of heat, then the metal spoon will become hot -> the metal spoon will get hot
