Q2/ A thermostat control with dial markings from 0 to 100 is used to regulate the temperature of an oil bath. A calibration plot on logarithmic coordinates of the temperature, T (°F), versus the dial setting, R, is a straight line that passes through the points (R1 = 20.0, T1=110.0 °F) and (R2 = 40.0, T2 = 250.0 °F). (a) Derive an equation for T (°F) in terms of R. (b) Estimate the thermostat setting needed to obtain a temperature of 320°F.
