Explanation:

When fireworks explode, sound and light are produced. These are examples of macroscopic outputs. Because, explosion from fireworks is an exothermic process which releases massive heat energy to the surroundings.

What is exothermic reaction?

Exothermic reaction are those which evolve heat energy to the surroundings. The change in enthalpy of the reaction is negative here. Whereas, in an endothermic reaction energy is absorbed by the reactants. Exothermic reactions sometimes result in massive explosions. The heat energy released to the surroundings from the fire works is at the macroscopic level.

The small scale process or quantity that cannot be measured using normal scales are called microscopic units. Therefore, the sound, light, and heat from the explosion all are macroscopic outputs.

What is the difference between exothermic and endothermic reactions?

Exothermic reactions release heat energy to the surroundings, while endothermic reactions absorb heat energy from the surroundings.
