Gibbs Free Energy

Why is Delta U a state function when Q+ W are both path functions?

How can two-path functions equal a state function?

With U, we only consider it at specific points in time rather than considering how specifically the internal energy of a system has changed.

Because heat and work are related to delta U directly as the two different methods showing how energy is transferred in and out of the system. Say delta U was +2kJ, the q and w could be any combination of energy values as long as the sum is +2kJ.
