It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.

The melting of ice cubes is a exothermic reaction?
No, it is a physical change, not a chemical reaction.
If a physical or chemical change gives off heat energy it is?
an exothermic process
Is melting of ice a physical process or a chemical process?
Physical. The chemical makeup of the water doesn't change, and no heat is absorbed or discharged (endo/exothermic).
What is an exothermic process?
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.
Is a bicycle changes color as it rusts a chemical or a physical change?
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'.
Who discovered physical and chemical change?
Nobody; exothermic reactions exist independent of our will.
Is freezing an example of an exothermic chemical change?
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
What change is exothermic chemical change?
A reaction in which heat is given out.
When energy is given off as heat the physical change is said to be?
Exothermic
Is Cleaning a painted surface with acid a chemical or physical change?
Chemical broooooooooooooooo niga
Is the reaction of magnesium sulfate and water exothermic or endothermic?
It is not a chemical reaction, it is dissolution; this physical process is exothermic.
Is peeling an apple a physical or chemical change?
it is a chemical change
