What is the difference between an exothermic and endothermic reaction?

Exothermic = A reaction that transfers energy to its souroundings therefore the temperature of the sourounding increases (gets hotter). Can you think of an example? E.g. combustion, neutralisation. As heat is released the products have less energy than the reactantsDiagram of Beaker with arrows pointing outwards to represent energy loss to the souroundings
Endothermic= A reaction that takes in energy from its souroundings so the temperatue decreases (gets colder). Example includes thermal decomposition. Heat is absorbed, the products have more energy than the reactants. diagram
