Determining entropy change

Is it correct to say that entropy increases in a reaction where there is:
-increase in the number of gas molecules
-phase changes from solid->liquid->aqueous->gas (is this order correct?)

Are there any other cases?

In general, if there are fewer bonds, then entropy will increase, which often does show up as products with more gas molecules. And I'm pretty certain that is the correct order for phase changes.

Entropy increases:

more moles/particles of gas present
phase changes from solid to liquid to gas
molecules are in solution
more moles of products are made in a reaction

Temperature!

Entropy increases with temperature despite its equation being S=q/t

True, S=Q/T is applicable for constant temperature only. A better way to write that is ΔS=ΔQ/T.
