Question

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

Open in App

Solution

For isolated system there is no transfer of energy as heat, i.e., q = 0 and there is no transfer of energy as work, W = 0. According to the first law of thermodynamics
$Δ U = q + W Δ U = 0 + 0 = 0$
