Is Delta G a state function since it is additive?

yes, it involves enthalpy and temperature

Free energy is a state function, because it involves enthalpy and entropy, two other state functions.

The acronym "PD TV HUGS" help with remembering the state functions. They are: pressure, density, temperature, volume, enthalpy, internal energy, gibbs free energy, and entropy.

Work is NOT a state function because it depends on the path taken to get to the final result.

Work (w) and heat (q) are NOT state functions.

Delta G, or just Gibbs free energy, is a state function. This means that you can apply the properties state functions have such as the properties you use for enthalpy and entropy.

Yes because it is inclusive of two other state functions

Yes delta G is a state function because it is defined by other state functions.

Delta G is a state function, as it is made up of other state functions since as enthalpy and entropy

yes it is a state function, and can be added like enthalpy and calculated in very similar ways

Basically anything that isn't part of "PD TV HUGS" are not state functions.

Examples of things we've learned now that are NOT state functions would be: work (w), heat (q), and cell potential (E)

Gibbs Free Energy is a state function, all the properties of the equation deltaG = deltaH - T(deltaS) are also state functions.

Yes and I remember because Lyndon said once he was "Feeling a little Pressured and Dense. He wished he could just watch TV and get HUGS.
(PV TV HUGS).

It's a state function due to its upbringing that stems from the incorporation of two other state functions: Enthalpy and Entropy
