mfb said:I don't understand your description at all. There is no time-evolution that has to be taken into account with perfect isolation, room temperature is not relevant at all, and no melting points (apart from ice at 0 C) are relevant
I didn't assume time as a factor at all, I assumed heat energy transfer. 0c-32f to 50c-122f to 88f-31.1c with a weighted average of 25c or 77.00f Is the math wrong?
Maybe I misunderstood the first calculation. 20c=68f -0c-32f dropping to -18c or -0.4f I understand that alcohol lowers the melting temp of water below its freezing point so it melts and gives up its energy even in a cold environment. But I didn't take equilibrium into account with the first calculation
