Reversible is something that can return to a previous condition or state.
Reversible is a term in our language that comes from the word reversus. It is an adjective that refers to the possibility of something returning to its previous condition or state .
For example: “The situation of the building is reversible: with investment and work, it is possible for the construction to recover its former splendor” , “Experts stated that the damage suffered by the sculpture is reversible” , “If global warming continues to advance, "Antarctic melting will no longer be reversible."
The term reversible can be applied to that which can be reversed (turn around, go back). Suppose a famous painting is attacked by an unbalanced person who wishes to destroy it. When analyzing the damage, an art restorer ensures that it is reversible: this means that, following certain techniques, the painting in question can recover its original appearance. If the damage were irreversible, however, there would be no way to restore it.
Reversible actions in computing
Computing refers to reversible actions to describe everything that the user can "undo" while working with a specific application. Today, all editing programs provide the ability to override a variable number of actions, with certain exceptions, so that an error or distraction doesn't throw away hours and days of work; This feature is available in word processors, raster graphics editors such as Photoshop , three-dimensional modeling and animation tools, and audio editors.
Some computer tools also allow the user to adjust the number of reversible actions per session, since this affects the use of RAM memory: the more actions possible to reverse, the greater the memory consumption, and not all computers have the sufficient capacity for this number to be very high, especially when the type of document includes very "heavy" elements, such as graphics or audio recordings. Generally, since this decision belongs to the group of "advanced properties" of a program, this is only possible in very specific design applications.
There are chemical reactions that are reversible.
The term in chemistry
In the field of chemistry , the reaction whose products are combined again to generate the reactants is called a reversible reaction . To represent it in an equation, a double arrow is used, which points in the direction of each reaction : for the direct one it points to the right, while the reverse one is located to the left.
This concept appeared in 1803 and was presented by the Savoyard chemist Claude Louis Berthollet , after noticing that sodium carbonate crystals were forming on the edge of a salt mine. Until then, scientists believed that there was only one direction for every chemical reaction. Berthollet understood that the reason the reaction leaned in the opposite direction than expected was due to the excess salt in the water.
Science , on the other hand, speaks of a reversible process when it has gone from an initial state to a final state and can then return to its original properties.
Reversible clothing
Reversible clothing , finally, is made up of garments that can be worn upside down or upside down: “My mother gave me a reversible jacket that is red on one side and purple on the other.”
As often happens in the world of fashion , reversible garments have appeared on the market on more than one occasion, achieving special acceptance by children and young people. One of its main advantages is the possibility of offering two different looks , which can lead observers to believe that they are two individual garments.
