Grade upto college level Thermal Physics
A thermocouple is formed from two different metals, joined at two point in such a way that a small voltage is produced when the two junctions are at different temperatures. In a particular iron- constantan thermocouple, with one junction held at 0°C , the output voltage varies linearly from 0 to 28.0 mV as the temperature of the other junction is raised from 0 to 510°C. Find the temperature of the variable junction when the thermocouple output is 10.2 mV.
