Different gases will have different inversion temperatures usually the hydrogen and helium will have very low maximum inversion temperatures so, cooling by using throttling for these gases is slightly difficult.
Answer: Option 1
Above the inversion temperature joul thomson coefficient $$\left( \mu \right) = {\left( {\frac{{\partial T}}{{\partial P}}} \right)_H}{\text{ is }} - {\text{ve}}$$
So, on decreasing the pressure (throttling) the temperature...
Answer: Option 2
For almost all the gases the maximum inversion temperature is above the room temperature but for gases like $${H_2}.$$ The inversion temperatures are 200K and 24K respectively...
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...
Answer: Option 4
In a manufacturing process, Production manager takes the decisions as to what quantities and which process or processes are to be used so that the cost is...
Answer: Option 3
For cooling to take place by throttling the Joule-Thomson coefficient must be negative. $${\left( {\frac{{\partial T}}{{\partial P}}} \right)_H} = - VE.$$
