Question

What is exothermic change and endothermic change, and also give example?? ​

Answer 1

A good example of an endothermic reaction is photosynthesis. Combustion is an example of an exothermic reaction. The categorization of a reaction as endo- or exothermic depends on the net heat transfer. In any given reaction, heat is both absorbed and released.

Answer 2

exothermic change.....and exothermic change is a change in which a substance evolves heat

eg...air conditioner absorbs heat and gives us a cooling affect.

endothermic change is a change in which a substance gives out heat.
