To describe: the source of heat, light, sound and electricity.
Explanation of Solution
Introduction:
An exothermic reaction is a
In exothermic reaction, the free energy of the product is less than the free energy of the reactant. The difference of this free energy is released in the form of heat, light, sound and electricity.
Conclusion:
Hence, free energy is the source.
