Statement 1: When a real gas undergoes adiabatic free expansion, its internal energy changes.
Statement 2: In adiabatic free expansion of any gas, q = 0 and w = 0.
Options:
Answer:
D
Solution:
Free expansion: Pext=0⇒ w=0; adiabatic ⇒ q=0 for ideal or real gas: II correct. Then Δ U=q+w=0 for the real gas too. The temperature of a real gas may change, but its internal energy does not. I is incorrect. Answer (d).
