State functions in thermodynamics

  1. Jul 17, 2011 #1
    The terms internal energy, enthalpy, entropy are state functions. Are change in internal energy([itex]\Delta[/itex]U or [itex]\Delta[/itex]E),change in enthalpy([itex]\Delta[/itex]H) and change in entropy([itex]\Delta[/itex]S) state functions?

    No, because they depend not only on the current state but also on a previous state. However, it is true that these functions do not depend on the path taken between the two states.
