The temperature of the system decreases in an

A

Adiabatic compression

B

Isothermal compression

C

Isothermal expansion

D

Adiabatic expansion

Text Solution

Verified by Experts

The correct Answer is:
D
When a real gas is forced through a prorus 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.
