Entropy of Universe?

Question

Hi U will read & listen HEAT DEATH of our planet and may be universe,,,,but me think not heat 4 universe,becoz me think that entropy of universe is constant at broad sense,as universe expanding,so it become cooler graudlly,so there will be balance,
What U think(me talking about our whole universe not our planet earth)???

Answer 1

Entropy of Universe is increasing ......
Entropy is nothing but randomness

Answer 2

Entropy is not just about heat as you are thinking. It is more basically about randomness. This randomness can be caused not neccessarily only by heating. In a chemical reaction, entropy changes are taking place but does not neccessarily get manifested in the form of heat. With each and every exothermic reaction that's taking place around us, the entropy increases. Exothermic reactions are naturally more favoured, as can be seen by the Gibbs' Helmholtz eqn. So we say that entropy of the universe, in general, increases. In any case, the expansion of the universe does not produce so much cooling as to slow down the rise of entropy. Imagine, if the entropy of the universe remains constant, nothing would break, gases would not move around, and conversion of matter from one phase to another would not be possible. Some scientists are suggesting that zillions of years down the line, entropy may actually be reversed!!!

Answer 3

One form of entropy is illness. once you open a %. of enjoying cards, each and every of the hearts are mutually and in series from ace to king; an identical with spades, golf equipment and diamonds. in case you drop the deck on the floor and %. it up, a number of the enjoying cards will possibly be out of order. The extra situations you drop it and %. it up, the extra illness (entropy) would be modern-day. as quickly as the deck is carefully shuffled, its entropy has reached optimum. Then, it could get closer to being so as in a single of two procedures---random threat or exterior intervention (by potential of a guy or woman stacking the deck). A deck of enjoying cards tumbling in a huge squirel cange is an occasion of a closed equipment (regardless of if there is not any such element as a splendidly closed equipment). For the enjoying cards interior the squirel cage to finally end up so as, there could desire to be an enter of dis-entropy from exterior. Earth isn't a closed equipment. It gets low entropy seen mild from the sunlight and radiates intense entropy warmth ratiation into area. What maintains to be at the back of is dis-entropy interior the form of life. I disagree with people who declare the universe is a closed equipment. If the universe is countless, that on my own makes the question of open or closed indeterminate. there is likewise the situation of dark capability, which seems to come lower back from exterior our universe. dark capability creates new area, it relatively is a limiteless warmth sink; so an increasing universe isn't a closed equipment. I relatively have my own Fractal Foam kind of Universes wherein our universe is barely one in a limiteless scale-sensible series. each and every smaller-scale universe exports its entropy to the subsequent super-scale universe, and time reversal converts that to an enter of dis-entropy into the better-scale universe.

Answer 4

Excuse me, I do not think that the entropy of universe is constant, but it is steadily increasing. It is the energy which is constant but not the entropy

Answer 5

entopy of the universe is increasing
according to second law of thermodynamics.
thats it

Answer 6

Look! such questions can't be answered till we don't find the nature of dark energy...
