Question
Predict the change in internal energy for an isolated system at constant volume.
✓

Answer

For isolated system, there is no transfer of energy as heat or as work i.e., w = 0 and q = 0. According to the first law of thermodynamics.$\Delta\text{U}=\text{q}+\text{w}$
= 0 + 0 = 0$\therefore\Delta\text{U}=0$
