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

$\therefore\Delta\text{U}=0$
