Chemical Thermodynamics Question 64
Question: The temperature of the system decreases in an [KCET 2005]
Options:
A) Adiabatic compression
B) Isothermal compression
C) Isothermal expansion
D) Adiabatic expansion
Show Answer
Answer:
Correct Answer: D
Solution:
When a real gas is forced through a porous plug into a region of low pressure, it is found that due to expansion, the gas on the side of low pressure gets cooled. The phenomenon of producing lowering of temperature when a gas is made to expand adiabatically from a region of high pressure into a region of low pressure is known as Joule-Thomson effect.
