of an ideal gas is heated from to keeping its (i) volume constant (ii) pressure constant. Let and denote the change in the internal energy of the gas due to process (i) and (ii), respectively. Then, which of the following shall be true?
View answer and explanation
Correct option: B
Option A () is incorrect. For a constant volume process, all heat added goes into internal energy. For a constant pressure process, some heat is used for work, so the internal energy change is less.
