The Joule-Thomson coefficient and change in temperature during Joule- Thomson effect is given by 

which one is correct about αT to produce cooling and heating effect respectively?
  • a)
    αT = 1 for both cooling and heating 
  • b)
    αT < 1 for cooling effect
    αT > 1 for heating effect
  • c)
    αT > 1 for cooling effect 
    αT = 0 for heating effect
  • d)
    αT>1 for cooling effect
    α T< 1 for heating effect
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
The Joule-Thomson coefficient and change in temperature during Joule- ...
dT = 
dP: represents the fall in temperature which is always negative.
Now dT is negative if αT > 1
So, cooling is produced
dT is positive if  or heating is produced.
