Question

Stainless steel pans are usually provided with copper bottoms. The reason for this could be that
1. copper bottom makes the pan more durable.
2. such pans appear colourful.
3. copper is a better conductor of heat than the stainless steel.
4. copper is easier to clean than the stainless steel.

Answer 1

Correct Answer - Option 3 : copper is a better conductor of heat than the stainless steel.

Concept:

Metals:

• They are opaque, lustrous elements that are good conductors of heat and electricity.
• Most metals malleable and ductile and are, in general, denser than the other elemental substances. 
• Examples of metals are iron, copper, aluminum, calcium, magnesium, etc.

Some physical properties of metals are listed below.

• Lustrous (shiny) in nature
• Opaque
• Metal is a good conductor of electricity and heat
• High Density
• High melting point
• Mouldable (Malleable)
• Ductile (converted into thin sheets)
• At room temperature, it is in solid form except for mercury.

Explanation:

• Stainless steel pans are usually provided with copper bottoms because copper is a good conductor of heat than stainless steel and copper cooks the food becomes faster.
• Hence, we can conclude that Stainless steel pans are usually provided with copper bottoms. The reason for this could be that copper is a better conductor of heat than stainless steel.
