syntyhesis: process of making something ex. protein synthesis
Decompose: To become broken down into components; disintegrate
endo: releasing heat and energy ex. fire
exo: absorbing heat and energy ex. ice cube
The two terms are probably used most often to describe chemical reactions - whether or not they absorb or require heat (endothermic) or create release heat (exothermic). However, since the terms simply mean "absorbing heat", and "giving off heat", they can be used to describe any such event, physical, chemical or nulear. Ray
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
Endothermic - is something that absorbs heat.
The reaction is exothermic
Platypuses are endothermic. Platypuses are monotremes, which are egg-laying mammals, and all mammals are endothermic. This means that they regulate their body temperature by internal processes and that their body temperature is constant.
This is a chemical change because once the substances are put together to form a gas it cannot be changed.
The combustion of magnesium is an exothermic reaction because it releases heat energy. The bright white light and high temperatures produced in the reaction are characteristics of exothermic reactions.
Thedecompositionof water is endothermic since energy is required to break up the bonds between the hydrogen and oxygen in the water molecule. Therefore the decomposition of water absorbs energy, making the reaction an endothermic one.

nope. Endothermic reactions involve the reactants including heat, but ending up with colder products. But you started with wood without heat, and ended up with a hot fire. This is an exothermic reaction.
If the forward reaction is exothermic then the back reaction would be endothermic. This happens because it upholds the law of conservation of energy, which says that energy cannot be created or destroyed.
In an exothermic reaction, heat is released from the system to the surroundings, resulting in a temperature increase in the surroundings. The heat lost by the system is gained by the surroundings, increasing their thermal energy.
Exothermic means it gives out heat or energy
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
It seems like you're referring to the term "exothermic." Exothermic reactions release heat to their surroundings, resulting in an increase in temperature. This energy release is usually in the form of heat, but it can also manifest as light. Examples of exothermic reactions include combustion and neutralization reactions.
