Physics. Repeat Problem 1 for the CTE of copper (column 3 of Table 1).

Problem 1

Physics. The coefficient of thermal expansion (CTE) is a measure of the expansion of an object subjected to extreme temperatures. To model this coefficient, we use a Michaelis–Menten function of the form

where C = CTE, T is temperature in K (degrees Kelvin), and Cmax and M are constants. Table 1† lists the coefficients of thermal expansion for nickel and for copper at various temperatures.

(A) Plot the points in columns 1 and 2 of Table 1 on graph paper and estimate Cmax to the nearest integer. To estimate M, add the horizontal line to your graph, connect successive points on the graph with straight-line segments, and estimate the value of T (to the nearest multiple of fifty) that satisfies .

(B) Use the constants and M from part (A) to form a Michaelis–Menten function for the CTE of nickel.

(C) Use the function from part (B) to estimate the CTE of nickel at 600 K and to estimate the temperature when the CTE of nickel is 12.
