For a van der Waals gas, the internal energy U

Show Hint

Keep these distinctions in mind for exams:
• Ideal Gas: Internal energy \(U = f(T)\) (only depends on Temperature).
• Real/van der Waals Gas: Internal energy \(U = f(T, V)\) (both Temperature and Volume matter due to attractive intermolecular forces represented by the parameter \(a\)).
