Answer:

The correct answer is given as follows.

Explanation:

A fire started by striking a match and lighting crumpled paper under some logs in a fireplace involves a series of energy transfer phenomena that results in people heating themselves for being close to the fireplace. First, the potential energy from the match and the person that holds the match is transformed into kinetic energy, allowing the match to be lighted. This scenario is known as a exothermic reaction, because energy is released when the match is ignited and growths even more when the match is tossed into the crumpled paper under some logs heating the whole system. As a exothermic reaction, the fire releases heat to the surroundings including nearby people. Inversely, if there is ice melting near to the fireplace, the ice will be absorbing energy in what is known as an endothermic reaction.

Burning of match is the example of exothermic energy.

The potential energy from the match and the person that holds the match is transformed into kinetic energy which is responsible for the ignition of fire. This process is called exothermic reaction because energy is released when the match is ignited. This small ignition causes the burning of paper and then the whole system of logs.

As a exothermic reaction, the fire releases heat to the surrounding environment including people present near the fire. Endothermic energy is the absorption of heat energy from the surrounding so we can conclude that burning of match is the example of exothermic energy.
