Chapter 16: Problem 8

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 take advantage of the excellent heat conductivity of these metals for even heat distribution, while utilizing the durability and non-reactive properties of stainless steel.

Step by step solution

01

Understand the properties of Stainless Steel

It is important to know that stainless steel is actually an alloy that consists mostly of iron. It is durable, rust-resistant, and doesn't react with the food. However, it's not particularly good at conducting heat. This conductivity is necessary for even heat distribution which is desired in cookware.
02

Role of Copper and Aluminum

Aluminum and copper, on the other hand, are excellent heat conductors. They are used to ensure that heat from the cooktop spreads evenly across the bottom of the pot or pan.
03

Final Conclusion

Therefore, combining stainless steel with a layer of aluminum or copper combines the benefits of both materials. The stainless steel provides durability and no reaction with food, while the copper/aluminum core ensures that the heat is evenly distributed.

The outdoor temperature rises by \(10^{\circ} \mathrm{C}\). What's that rise in Fahrenheit?

You bring a \(350-\mathrm{g}\) wrench into the house from your car. The house is \(15^{\circ} \mathrm{C}\) warmer than the car, and it takes \(2.52 \mathrm{kJ}\) to warm the wrench by this amount. Find (a) the heat capacity of the wrench and (b) the specific heat of the metal it's made from.

An electric current passes through a metal strip \(0.50 \mathrm{cm}\) by \(5.0 \mathrm{cm}\) by \(0.10 \mathrm{mm},\) heating it at a rate of \(50 \mathrm{W} .\) The strip has emissivity \(e=1\) and its surroundings are at \(300 \mathrm{K}\). What will be the strip's temperature if it's enclosed in (a) a vacuum boule transparent to all radiation and (b) an insulating box with thermal resistance \(R=8.0 \mathrm{K} / \mathrm{W}\) that blocks all radiation?
