Problem
Out of the following properties how many are state functions? Heat enthalpy, Internal energy, Temperature, , Work, Heat, Specific heat, ResistanceIntuitive explanation
A state function depends only on the current state of a system, not on how it got there—think of it like altitude on a mountain, which is the same whether you hiked or drove up. The key is recognizing that path-dependent quantities like heat and work are not state functions, while properties that describe the system's condition right now (internal energy, enthalpy, temperature, cell potential) are. Specific heat and resistance describe material properties, not the state of a particular system, so they fall into a different category entirely.
