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.
