A change of state from solid to liquid, or liquid to gas, or directly solid to gas., all indicate an increase in entropy.
Also an increase in moles from reactants to products.
The Classic example being the thermal decomposition of calcium carbonate
CaCO3(s) ==Heat==> CaO(s) + CO2(g)
You have a gas liberated from a solid, so an increase in entropy.
You also have one mole reactant increasing to two
moles of product, so again an increase in entropy.
thawing
The increase in entropy will depend on the physical states of the reactants and products. If the reactants are solid and the products are gaseous, there will likely be an increase in entropy due to the increase in disorder. However, if both the reactants and products are in the same state, the change in entropy may be minimal.
CH4(g) + H2O(g) CO(g) + 3H2(g)
At high temperature the entropy increase.
Yes, the hydrophobic effect contributes to an increase in entropy.
thawing
At high temperature the entropy increase.
thawing
A gas typically increases the entropy much more than the increase in moles.
Yes. Diffusion will increase the entropy.
A perfectly ordered crystal at absolute zero is not apt to increase entropy, as entropy tends to increase with higher temperatures and disorder.
The increase in entropy will depend on the physical states of the reactants and products. If the reactants are solid and the products are gaseous, there will likely be an increase in entropy due to the increase in disorder.

CH4(g) + H2O(g) CO(g) + 3H2(g)
At high temperature the entropy increase.
The entropy of the universe is increasing
Yes, the hydrophobic effect contributes to an increase in entropy.
In a nutshell, yes. The water will go from a higher concentration to a lower concentration to increase the entropy of the lower concentration area. The increase in entropy of the lower concentration area would be greater than the loss of entropy of the higher concentration giving you a NET increase in total entropy.
