Question

Stainless steel cooking pans are preferred with extra copper bottom. Why?

Solution

The conductivity of copper is large as compared to the conductivity of steel.
Therefore when a cooking pan, fitted with extra copper sheet, is placed over a flame, more heat passes to the food.
This helps in cooking the food fast.
