water is boiled at sea level in a 30cm diameter mechanically polished AISI 304 stainless steel pan placed on top of a 3kW electric burner. if 60% of the heat generated by the burner is transfereed to the water during boiling,determine the temperature of the inner surface of the bottom of the pan. also determine the temperature difference between the inner and outer surfaces of the bottom of the pan if it is 6mm thick.
