What is the value of Joule-Thomson co-efficient for an ideal gas?
Answer: Option 3 The joule Thomson coefficient is given as $${\mu _i} = {\left( {\frac{{\partial T}}{{\partial P}}} \right)_H},$$ And since for an ideal gas enthalpy is strictly only function...

Gases are cooled in Joule-Thomson expansion, when it is __________ inversion temperature.?
Answer: Option 1 Above the inversion temperature joule-thomson coefficient $${\left( {\frac{{\partial T}}{{\partial P}}} \right)_H} = - ve$$ So, by throttling (decreasing the pressure) the temperature increases and hence heating. Below the inversion...

All gases except __________ shows a cooling effect during throttling process at atmospheric temperature and pressure.?
Answer: Option 4 Since all the gases except $${H_2}$$ $$He$$ etc, have maximum inversion point greater than atmospheric (room) temperature cooling can take place by throttling if the initial conditions...

The value of Joule-Thomson co-efficient, in case where cooling occurs after the throttling process is?
Answer: Option 3 For cooling to take place by throttling the Joule-Thomson coefficient must be negative. $${\left( {\frac{{\partial T}}{{\partial P}}} \right)_H} = - VE.$$
