The electric circuit shown below is designed to measure the temperature of the gas in a chamber.

The resistor R represents a temperature sensor enclosed in the chamber. The resistance R, in Ω, is related to the temperature T, in °C, by the equation R = R₀ + k_T In this device, assume R₀ = 100 Ω and k = 0.5. The voltmeter displays the value of the voltage, V_m , across the sensor. This voltage V_m indicates the temperature, T, of the gas according to the equation

Suppose the voltmeter voltage is constrained to the range V_min = 12 volts ≤ V_m ≤ V_max = 18 volts. Write a program that accepts a value of V_m and checks that it’s between 12 and 18. The program should return the gas temperature in degrees Celsius when V_m is between 12 and 18 and an error message when it isn’t.

R= 75 2 11.43 V e Voltmeter V, = 20 V V.
