Delta S= Sum of Entropy(products)- Sum of Entropy(reactants.
Greek
I don't think entropy can get less than zero
yes
Yes.
The lowest possible entropy occurs in a system at absolute zero temperature. At this point, the system is in a state of maximal order, with all particles at rest and in perfect arrangement, resulting in zero entropy.
Entropy is at its lowest point, or 0, in a system when it is in a state of perfect order and organization, with no randomness or disorder present.
solid crystal
Solid carbon dioxide, also known as dry ice, has the lowest entropy among the different forms of carbon dioxide. In its solid state, the molecules are tightly packed together, resulting in a more ordered arrangement and therefore lower entropy compared to gaseous or liquid states.
Higher is the energy of the state, lower will be its rigidity. Hence, we can say that solids have lowest state of energy because they are most rigid and gases have the highest state of energy since they are fluid in nature and don't have any rigidity.
Solid to liquid
This is called entropy.
Entropy is the measure of system randomness.
The entropy change in a reaction can be calculated by comparing the entropy of the products to the entropy of the reactants. Without specific entropy values provided, it is difficult to determine the exact change. However, in general, the entropy change is positive in reactions where the products have higher entropy than the reactants, indicating an increase in disorder.
It's not that entropy can't be reversed, it's that the entropy of the universe is always increasing. That means that while you can reduce the entropy of something, the entropy of another thing must go up even more so that in total, the entropy goes up.
The entropy of the universe is increasing
The units of entropy are joules per kelvin (J/K). Entropy is a measure of disorder in a system, with higher entropy indicating greater disorder. The relationship between entropy and disorder is that as entropy increases, the disorder in a system also increases.
