Due to temperature difference A T, heat is conducted through an aluminium plate that is 0.046 m thick. The plate is then replaced by a stainless steel plate that has the same temperature difference and cross-sectional area. How thick should the steel plate be to maintain the same heat/second of conductivity. The thermal conductivity of aluminium is 205 W/(m.K) and for stainless steel is 16 W/( m.K) A 2.4 mm B 4.2 mm C 1 cm D 3.5 mm
