Q141

__________ decreases during adiabatic throttling of a perfect gas.

A.
Entropy
B.
Temperature
C.
Enthalpy
D.
Pressure
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
During Throttling under adiabatic conditions the pressure energy decreases because some of the pressure energy gets lost as frictional losses thereby increase in intermolecular energy. Hence always there will be loss in pressure energy there by reducing the pressure.
