The Seebeck voltage (?) to relative temperature (T) conversion for a copper-constantan thermocouple with an ice point (0.00°C) reference is given over the range -160.°C to 400.°C by T = a₀ a₁? + a₂?² + a₃?³ + ... + a₇?⁷ , where T is in °C and ? is the Seebeck voltage in microvolts (i.e., 10-6 V). The polynomial coefficients given by the National Bureau of Standards are

a₀ = 0.100860910

a₁ = 25727.94369

a₂ = -767345.8295

a₃ = 78025595.81

a₄ = -9247486589

a₅ = 6.97688 × 10¹¹

a₆ = -2.66192 × 10¹³

a₇ = 3.94078 × 10¹⁴

a. Write an interactive computer program that asks the user for the thermocouple voltage (in the proper units) and returns the temperature, Seebeck, Peltier, and difference in Kelvin coefficients (in proper units) to the screen.

b. Plot the Seebeck voltage and the Seebeck and Peltier coefficients vs. temperature over the temperature range of 100.°C to 400.°C using at least 100 points per curve.
