Entropy question

Please explain where I am going wrong in my line of reasoning:

1)Entropy is a measure of disorder; the higher the disorder, the higher the entropy.
2)Entropy generally tends to increase and the universe prefers a higher state of entropy.
3)"Entropy increases with number, volume, and temperature" - EK Chemistry 6th Edition, pg 60 (left hand column)

If all of the above are true, why doesn't the temperature of the universe increase spontaneously since the universe prefers a higher level of disorder?

just because an increase in temperature causes an increase in entropy does NOT mean that an increase in entropy will cause an increase in temperature.

Nothing in your reasoning suggests that the temperature of the universe would spontaneously increase... your reasoning only suggests that entropy tends to increase with an increase in temperature. Be careful with these truisms; make sure you understand the formulas from which they are derived.

2) money tends to increase (i.e. inflation) and trozman prefers money
3) money increases with having a better job

So umm, why isn't money falling into my lap? Why can't I spontaneously get a better job? Why does this logic not work?

if i punch you in the face, your face will hurt.

just because your face hurts, doesn't mean i punched you in the face.

HAHA...Awesome analogy!

HAHA...Awesome analogy!

I've studied kung fu for about 10 years.

That analogy resonated with me beautifully.😍

The second law says the universe will tend to a state of maximum entropy. The stars will all burn out eventually, protons decay and fall apart, black holes will evaporate, and eventually all matter exists only in the form of photons. At this point the universe is essentially burned out. There will be no more free energy left. For this to actually happen, assumptions are made about the universe geometry, but that is what theory says.

You're thinking of temperature in terms of a gas in a bottle or something. Temperature as most people know it is the effect of atomic collisions. As pressure increases (volume decreases), and collisions become more violent, therefore things 'feel' hotter to you. The temperature in the earth's upper atomsphere is something like 2000F, but if you stuck your hand out of a spaceship to feel up there, it would freeze instantly. Sure, the molecules up that high have insane amounts of energy, but they are incredibly scarce.

What will happen is the 'temperature' of the universe will approach absolute zero even though the entropy has reached a maximum level.

So, it's difficult to understand what you mean by 'temperature' of the universe.

and that's what I tried explaining to the jury
