Thermal Properties of Matter - Result Question 6

6. If the cold junction of a thermo-couple is kept at 0C and the hot junction is kept at TC then the relation between neutral temperature (Tn) and temperature of inversion (Ti) is [2007]

(a) Tn=2Ti

(b) Tn=TiT

(c) Tn=Ti+T

(d) Tn=Ti/2

Show Answer

Answer:

Correct Answer: 6. (d)

Solution:

  1. (d) Since Tn=Ti+TC2= Neutral temperature

Tn=Ti+02=Ti2

[Tc=0C=. temperature of cold junction ]
