query about some data value

hello @lucentdan , just wanted to know how you calculate this value and why it is always constent over temperature. in this function.

def standardGibbsChangeSolid(temperature):
    return (-907100 + 175*temperature)

H = -907100 --> ok S = 175 --> didnt understand how?

Can you please explain please??

I pulled this example from Gaskell. This is a standard form for the change in entropy for a phase change? That should be read as \Delta S, does that help? Sorry if I'm not understanding.
