Delta in enthalpy and not entropy

[Rida Ismail 2E]

Can someone explain to me why there is a delta in front of the H and not the S? Dr. Lavelle spoke about this today but I still didn’t quite grasp the information.

There is also a delta for the entropy term because entropy is a state function.

[Bella Townsend]

you can calculate the change in both enthalpy and entropy. Both enthalpy and entropy are state functions

[Katie Kyan 2K]

There is also a delta in front of the entropy as it is a state function meaning that you can subtract its final and initial states.

There can be a delta (or change in) for enthalpy or entropy since both are state functions. The one equation where delta isn't used is the Boltzmann equation, S=k_BlnW, since it is calculating the entropy of the system for that many energy states as opposed to the change in entropy due to a change in the system (such as volume or temperature)

[Daria MacAuslan 1H]

The delta sign just smbolizes that there is a change in that specific value. Both entropy and enthalpy are state functions, and both of them can have calculated changes in their values.

[Ruby Richter 2L]

Just for clarification then the only case where entropy would not be calculated as delta is in the Boltzmann equation S=kBlnW?
