### Internal Energy

How is Internal Energy a state function if work and heat are both path functions?

Internal energy is considered a state function because the only thing that matter is the current value, not how this value was achieved. Having the same level of internal energy can be achieved different ways (such as having different heat and work values) so this is why it is a state function.

The change of internal energy does not depend on how the system got to the initial or final state.
