A copper-constantan thermocouple generates a voltage of 4.75 × 10-3 volts when the temperature of the hot junction is 110.0 oC and the reference junction is kept at a temperature of 0.0 oC. If the voltage is proportional to the difference in temperature between the junctions, what is the temperature of the hot junction when the voltage is 1.90 × 10-3 volts?
