In an isothermal process for an ideal gas, which statement is true?

Explanation:
Isothermal means the temperature stays the same. For an ideal gas, the internal energy depends only on temperature, so if T does not change, the internal energy also does not change. This makes the statement that the temperature remains constant and the internal energy does not change true. Energy can still flow as heat and do work, but those transfers cancel in terms of internal energy, so ΔU = 0.
