Question

How many of the following thermodynamic parameters are state functions? Heat ($q$), Work ($w$), Internal energy ($U$), Enthalpy ($H$), Entropy ($S$), Gibbs Free Energy ($G$), Temperature ($T$), Pressure ($P$).

Prashant Kotian · Accepted Answer

Correct answer: 6. A state function depends only on the current equilibrium state of the system, not the path taken to reach it. Internal energy (), Enthalpy (), Entropy (), Gibbs Free Energy (), Temperature (), and Pressure () are state functions (total of 6). Heat () and Work () are path functions.
