Chemistry Question on Thermodynamics
Joule Thomson expansion is:
A
isobaric
B
isothermal
C
iso-enthalpic
D
iso-entropic
Answer
iso-enthalpic
Explanation
Solution
Joule-Thomson effect is the phenomenon, in which the temperature of a gas, when it is made to expand adiabatically from a region of high pressure to a region of low pressure, suddenly decrease. The Joule-Thomson effect is iso-enthalpic process, as there is no change in enthalpy during process.
