Chapter 16: Problem 9

Stainless-steel cookware often has a layer of aluminum or copper embedded in the bottom. Why?

Short Answer

Expert verified
Stainless-steel cookware often has a layer of aluminum or copper embedded in the bottom to overcome the poor heat conductivity of stainless steel. These metals distribute heat evenly across the surface, ensuring the food is cooked evenly and preventing areas from overheating.

Step by step solution

01

Understand the properties of Stainless Steel

We start by understanding why stainless steel is widely used for cookware. Stainless steel is durable, corrosion-resistant, and does not react with food, which makes it a good material for cookware. However, one major drawback of stainless steel is its poor heat conductivity.
02

Explain the role of Aluminum or Copper

Now, we need to understand the role of aluminum or copper. Aluminum and copper are good heat conductors, meaning they distribute heat evenly across their surface. This helps in evenly cooking the food, preventing areas from overheating, which can result in burnt food.
03

Connect the purpose of both elements

The layer of aluminum or copper is embedded in the bottom of stainless-steel cookwares to overcome the poor heat conductivity of stainless steel. By doing so, manufacturers take advantage of the durability and non-reactive nature of stainless steel while ensuring even heat distribution with the help of aluminum or copper.
