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 candle wax melting exothermic?
no because when a substance changes its state of matter then it is NOT considered a chemical reaction or a chemical change.
What is released by an exothermic reaction?
what is released during a chemical reaction is ENERGY.
Is melting a penny an exothermic change?
Chemical, since it doesn't turn back.
Why are fireworks considered a chemical change?
they are actually considered exothermic change because they release energy.
Is exothermic a physical or a chemical change?
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.

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.
Describe the two types of energy changes that occur in a chemical reaction?
An exothermic reaction and the change between potential and kinetic.
What change is exothermic chemical change?
A reaction in which heat is given out.
A change of state where energy is given off?
Endothermic Reaction. Exothermic is a chemical reaction in which energy must be provided.
What Kinds of chemical changes?
Exothermic reactions. E.g. combustion, oxidation
Is burning coal for heat a chemical change?
Yes, it is an exothermic chemical reaction.
What type of change occurs when sodium and chlorine combine?
Chemical change and exothermic change
What is released by an exothermic reaction?
what is released during a chemical reaction is ENERGY.
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'.
