an increase in temperature

a decrease in temperature

luminescence

a color change

formation of water

bubbles

Explanation:

Effect of Temperature:

Exothermic reaction: Combination of reactants in a reaction, exhibits heat energy to the surrounding, as a result we feel heat on system.

In endothermic reaction it absorbs heat from surrounding so the system feel cool.

According to Le Chatelier's principle, if you increase the temperature you are increasing the amount of products, and so you shift the balance at equilibrium back toward reactants, meaning there will be more reactants left at equilibrium. The higher the temperature goes, the further the balance at equilibrium shifts back toward reactants

Luminescence: an exothermic reaction will generally be luminescent provided radiation rather than collisional. This processes remove the excess internal energy.

Formation of water: is exothermic, because water is a very low-energy compound. Generally, any hydrocarbon should burn with formation of water, which, again, is a combustion, so it is highly exothermic.

Bubbles: Formation of bubbles not always becomes exothermic, sometimes it is endothermic too.
