The Joule-Thompson effect describes the temperature change of a real gas or fluid when it is forced through a valve or porous plug while remaining insulated, so that no heat is exchanged with the environment. For a positive Joule- Thompson coefficient, the gas cools upon throttling.
A gas having a positive Joule-Thompson coefficient ( $\mu_J > 0$ ) when throttled will - (1) become warmer - (2) become cooler - (3) remain at the same temperature - (4) undergo heating and cooling both - (5) Question not attempted
