change in internal energy

U is a state property representing internal energy of a system. So in equations it represents the change in internal energy from initial and final states.

Delta U represents the change in the internal energy of a system

∆U= (U final-U initial)= change in internal energy

It represents the change in the internal energy of a system !

It is the final internal energy minus the initial internal energy of the system.

delta u is the change in internal energy

U is the internal energy so delta u would be the change in internal energy
