A reaction with a positive heat flow is called an endothermic reaction. In this type of reaction, energy is absorbed from the surroundings, resulting in a decrease in temperature of the surroundings. Common examples include photosynthesis and the dissolution of certain salts in water. During these reactions, the products have higher energy than the reactants due to the absorbed heat.
If heat is required for a reaction to occur, it is an endothermic reaction. Endothermic reactions absorb heat from their surroundings in order to proceed.
exothermic reaction
Any reaction that consumes energy, or has a positive delta(H), is called an endothermic reaction.
Decomposition reaction: CaCO3(s) --(heat)--> CaOs + CO2(g)
Reactions that are characteristic of negative heat flow are exothermic reactions. In these reactions, energy is released to the surroundings, usually in the form of heat, resulting in a decrease in the system's internal energy. Common examples include combustion and respiration, where bonds are broken and formed, releasing energy. The release of heat often leads to an increase in the temperature of the surroundings.
This is an exothermic reaction.

exothermic reaction
The type of reaction that involves oxygen and produces light and heat is a combustion reaction.
exothermic reaction. This type of reaction releases energy to the surroundings as heat.
Exothermic reaction gives free heat (energy).
