For an ideal gas, the internal energy change with respect to volume at constant temperature is zero
Is it true that for an ideal gas, the internal energy change with respect to volume at constant temperature is zero?
The internal energy of an ideal gas depends solely on its temperature and is independent of its volume (Joule's second law), making this statement a textbook definition that does not require citation.
Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked
The claim states a fundamental law of thermodynamics regarding ideal gases (often referred to as Joule's law or a direct consequence of the ideal gas equation and internal energy dependence solely on temperature). As a foundational definition taught in introductory physics and chemistry, it is common knowledge in thermodynamics and does not need empirical citation.
