Revered Members,
I want the answer for the following question
Joule Kelvin effect is to produce
a) high temperature b) moderate temperature c) low temperature d) temperature below 0.4K
I know Joule Kelvin effect is to produce low temperature by throttling process. So I guess,the answer should be either (c) or (d). But since specifically mentioned 0.4 K, i am confused.
Revered members, I solicit your help in this regard.
Thanks in advance.
