Class 11Physics2 Thermal Properties of Matter: Heat TransferHeat Conduction and Thermal Conductivity
DifficultThese days,people use steel utensils with copper bottoms. This is considered good for uniform heating of food. Explain this effect using the fact that copper is a better conductor of heat.
Copper is a much better conductor of heat than steel. When a copper layer is provided at the bottom of a steel vessel,it absorbs heat from the flame very quickly due to its high thermal conductivity.
Because copper spreads the heat rapidly across the entire base,it ensures uniform heating of the food inside the vessel.
This prevents the formation of hot spots and allows the food to be cooked more efficiently and quickly.
