Some cookware has a stainless steel interior (α=17.3×10−6k−1) and a copper bottom (α=17.0×10−6k−1) for better heat distribution. suppose an 8.0-in. pot of this construction is heated to 620 ∘c on the stove. part a if the initial temperature of the pot is 22 ∘c, what is the difference in diameter change for the copper and the steel?

0.0014352 inch

Explanation:

= Coefficient of linear expansion of steel =

= Coefficient of linear expansion of copper =

= Original diameter = 8 in

= Change in temperature

Change in diameter of steel

Change in diameter of copper

Difference in diameter is given by

The difference in diameter change for the copper and the steel is 0.0014352 inch
