Stainless steel cooking pans are perferred with extra copper bottoms. Why?

Options

A. copper is cheaper
B. conductivity of copper is more than that of stainless steel.
C. copper increases durability of the cooking pan
D. copper is a good reflector of heat

Answer

B

Explanation

The stainless steel cooking pans are preferred with an extra copper bottom because the thermal conductivity of copper `(385 Js^(-1) m^(-1)^@C^(-1))` is more than that of steel `(50.3 J s^(-1) m^(-1)^@ C^(-1))` and the food gets cooked easily.
