A temperature transmitter using a thermocouple has an output voltage of 10 mV. If the reference junction is at 25°C and the hot junction is at an unknown temperature, what is the temperature of the hot junction if the type of thermocouple being used is a K-type?
A. 255.5°C
B. 300.5°C
C. 350.5°C
D. 209.5°C
Answer:D
