Re: Entropy
Irreversible processes cause a change in entropy, whereas reversible processes have an entropy change of 0.

Re: Entropy
Kathy can you explain what you mean by that? What kind of example should we refer to understand that concept?

Re: Entropy
If entropy is always increasing, then in a non-spontaneous reaction what part of the reaction relates to the increase in entropy if we are using work to create order?

Re: Entropy
I understand that with a more massive substance, the higher the entropy. But, how can you distinguish in the level of entropy between a solid, a liquid, and a gas of the same substance?

Re: Entropy
Usually entropy increases from solid -> liquid -> gas because there's more disorder associated with a gas (molecules are free to move around and are not bounded) compared to that of a solid (molecules are in rigid structures).

Re: Entropy
A higher pressure would mean that a substance is more constricted to move around. The entropy would therefore be less when the pressure increases.
