all right you science fags
i've been searching for hours explanations for this but can't find anywhere so here i am

it's about absolute entropy formula
we have
S2-S1 = C ln(T2/T1)

if T1 = 0K then S1 = 0 so we have to integrate
(C/T)dT from 0 to T to get S

all right .. cool formula
what's the fucking point to integrate from 0 ? how does it gives us a value since ln(0+) = -∞ ?

let's say after integration, considering S at 0K = 0
we just have S at T = C ln(T)
kewl we can now calculate entropy of fucking anything
well .. what about something that is at a temperature of 1K ? S = still fucking zero ?
and at 0.5K S is fucking negative ?
i'm fucking lost help me
