In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
Q: passage: Isothermal processes are of special interest for ideal gases. This is a consequence of Joule's second law which states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. Thus, in an isothermal process the internal energy of an ideal gas is constant. This is a result of the fact that in an ideal gas there are no intermolecular forces. Note that this is true only for ideal gases; the internal energy depends on pressure as well as on temperature for liquids, solids, and real gases.
 question: is an isothermal change the internal energy of the ideal gas molecules?
A: 
Yes
