Question

Why do people prefer to use copper bottom vessels for cooking?

Answer 1

Hint: Comparison of heat conductivity of copper is needed with other elements.

Complete step by step solution:
Copper has excellent heat conductivity. It is durable and corrosion resistant too. All these characteristics make people prefer copper bottom vessels for cooking rather than vessels made of other materials and also the fact that heat spreads evenly in copper cookware than in traditional pots.

Additional information: Copper conducts five times better heat than iron (Fe) and twenty times better than stainless steel.

Note: Stainless steel is an alloy of iron with a minimum of 10.5% of chromium.
Heat conductivity of copper is 385.0 W/m K.
Heat conductivity of Iron is 79.5 W/m K.
Heat conductivity of copper > Heat conductivity of Iron
