(a) Digital medical thermometers determine temperature by measuring the resistance of a semiconductor device called a thermistor (which has α = – 0.0600 / ^oC) when it is at the same temperature as the patient. What is a patient’s temperature if the thermistor’s resistance at that temperature is 82.0% of its value at 37.0^oC (normal body temperature)?

(b) The negative value for α may not be maintained for very low temperatures. Discuss why and whether this is the case here?
