The temperature of the system decreases in an
A
Adiabatic compression
B
Isothermal compression
C
Isothermal expansion
D
Adiabatic expansion
Answer
Adiabatic expansion
Explanation
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.
