Smoke is a toxic gas produced by incomplete combustion. Combustion is a chemical oxidation reaction in which an element gives off energy in the form of heat and light. It is very common for combustion processes to give off a flare of fire at the top of which there is smoke composed of water, carbonic acid and toxic elements that vary according to the element that is burning.
Smoke is toxic to living beings in almost all its forms. The impurity of the elements that compose it pose a serious damage to the lungs of people and animals, plants also react negatively to this. It can cause many diseases and damage the environment, being one of the main agents or forms of pollution in the atmosphere that exists today.
The term smoke comes etymologically from the Latin Fumus, and is not only used to indicate the chemical result of burning an element, but also to name certain human actions to which they are related by their particular characteristics.
When we say colloquially that "there is a smokescreen" we are referring to an action in which one action is interposed to cover another. Smoke thanks to its dense property can be an obstacle to visibility. The pretense is also known as smoke, it consists of people who exalt themselves or believe that they have a hierarchy or capacity above others because they are given power or have more economic income.
