Internal Energy of an Ideal Gas – Rankers Physics

Kinetic Theory of Gases: Practice Problem & Solution

The internal energy of an ideal gas depends upon
Pressure
Temperature
Volume
Both (1) and (3)

Solution Explained:

To solve this problem, we apply the core principles of Kinetic Theory of Gases. Understanding the underlying formula is key to arriving at the correct answer below:

The internal energy of an ideal gas is a function of temperature only, as there are no intermolecular forces of attraction in an ideal gas. Therefore, \( U \propto T \).
