← ScienceWhich outcome is observed when increasing gas temperature in adiabatic compression with a van der Waals fluid?
A)Compressibility factor remains relatively constant
B)Internal energy increase deviates from ideals✓
C)Heat capacity decreases, approaching ideal gas
D)Entropy change is negligible in all cases
💡 Explanation
When increasing gas temperature during compression, the van der Waals forces cause non-ideal behavior, because the intermolecular attractions modify internal energy increase. Therefore, internal energy change deviates from ideal behavior rather than remaining nearly constant due to more complex molecular interactions. Compressibility isn't consistently maintained.
