In connecting extension leads to a chromel-alumel thermocouple that is measuring the

temperature of a fluid, a technician connects the leads the wrong way round (such that

the chromel extension lead is connected to the alumel thermocouple lead and vice

versa). The junction between the thermocouple and extension leads is at a temperature

of 100C and the reference junction is maintained at 0C in an ice bath. The technician measures an output emf of 12.212 mV at the open ends of the extension leads.

(a) What fluid temperature would be deduced from this measured emf?

(b) What is the true fluid temperature?
