Q36 of 62 Page 72

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

o An isolated system means no form of energy to be it heat or work can be transferred in any direction.


Hence , q=0. W =0 .


And according to 1st law of thermodynamics: ∆U= q + w (U=internal energy)


Therefore, change in internal energy for an isolated system ∆U = 0.
