Animals and plants use the chemical energy stored carbohydrates to fuel their own life processes, ultimately breaking down these carbohydrates into carbon dioxide, water, and heat in a process called aerobic respiration. The heat that is released from aerobic respiration dissipates into the environment. From this information, which of the examples of kinetic energy are:

A good example happens during the breakdown of food particles.

Explanation:

The chemical energy stored in food is a type of potential energy. Transformation of this energy into kinetic energy happens during chemical reactions that takes place during digestion. A good example of kinetic energy is therefore the breakdown of carbohydrates into carbon dioxide, water and heat.

energy and particles

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
