Question

Hi there. Could someone please dumb down and explain to me the concept of entropy? Thanks

Answer 1

Entropy is disorder! It's chaos. An increase of entropy would be something like ice melting. At it's solid form, the water molecules are closely packed and locked in a crystalline structure. There isn't much disorder. As you go to water, there is an increase in entropy - we can see this by it's fluidity. Finally, once you get water vapor, it's gaseous state, there is a lot of entropy. The water molecules are free to bounce around wherever they want to.

Answer 2

So nature likes it when there is more chaos. So change in entropy, Delta S likes to be positive. Delta S favors a reaction.

Answer 3

So if water looses temperature and freezes, it looses entropy?

Answer 4

yes it losses entropy and surroundings gain entropy

Answer 5

Preetha what happens when sodium sulphate is crystallised from a supersaturate solution?
