A change that releases energy in the form of heat to its environment.
An exothermic change is a change that releases heat. Combustion is an exothermic chemical reaction.Adding water to sulfuric acid releases heat, called exothermic heat of mixing. Exothermic changes are the opposite of endothermic changes that absorb heat when they take place.
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
Chemical, since it doesn't turn back.
they are actually considered exothermic change because they release energy.
Exothermic reactions. E.g. combustion, oxidation
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.

An exothermic reaction and the change between potential and kinetic.
A reaction in which heat is given out.
Exothermic reactions. E.g. combustion, oxidation
It is a chemical change. Here oxidation of Iron occurs and being oxidation reaction, it is 'exothermic' reaction.Through it takes prolonged period and it is difficult to observe it, you can deduct it. As 'all' oxidation reactions are 'exothermic'.

Jack recorded the exothermic change as the reaction progressed
Yes. Refer to endothermic and exothermic reactions to learn more.
