Question

Internal energy of a non - ideal gas depends upon

• A. Temperature
• B. Pressure
• C. Volume
• D. All of these

Answer 1

The correct option is D All of these

For an ideal gas internal energy is only a function of temperature. $U=f\left(T\right)$
Here, given gas is non - ideal in nature.
So, internal energy is a function of any two of the thermodynamic variables $P$,$V$ and $T$.
$U=f(P,V)$ or $U=f(T,V)$ or $U=f(T,P)$
$\therefore$ Internal energy of non - ideal gas depends upon Temperature, Pressure and volume.
Thus, option (d) is the correct answer.
