Chapter 8, Problem 29P
Estimated values of thermal conductivity of silicon at different temperatures are given in the following table.
| T(K) | 2 | 4 | 6 | 8 | 10 | 20 | 40 | 60 |
| k(W/m-K) | 46 | 300 | 820 | 1,560 | 2,300 | 5,000 | 3,500 | 2,100 |
| T(K) | 80 | 100 | 150 | 250 | 350 | 500 | 1,000 | 1,400 |
| k(W/m-K) | 1,350 | 900 | 400 | 190 | 120 | 75 | 30 | 20 |
(a) Make a plot of k versus T using log scale on both axes.
(b) Curve-fit the data vith a second-order polynomial y = ax2+ bx + C in which x = log(T) and y = log(k). Once the coefficients a, b, and c are determined, write an equation for k as a
(c) Repeat part (b) using a third-order polynomial.
