Question
In a thermo couple, thermo emf produced is 
per one degree difference of temperature between the two junctions. When the cold junction of such thermocouple is at 20°C, the thermo emf is 0.3mV. The temperature of the hot junction is
- 80°C
- 100°C
- 120°C
- 100 K
The correct answer is: 120°C
