Answer 2

Explanation:

• (b) A is correct, but B is wrong. The cold junction’s temperature is not dependent on the neutral temperature.
• The inversion temperature depends on the cold junction’s temperature.
• For a thermocouple, the neutral temperature’s value is constant. The neutral temperature depends on the materials’ nature and is independent of the cold junction’s temperature.
• Inversion temperature is dependent on the nature of the material and on the cold junction’s temperature.
