What Is Reversible, What Does It Mean?July 2, 2021
A physical, chemical and mechanical transformation that can change direction at any moment. The term is basically a physics term. Not all processes are reversible. But there are reversible processes in physics, chemistry, and mechanics. However, this reversal is not equivalent. Higher forms of energy can easily transform into lower forms of energy, but lower forms of energy cannot transform into higher forms of energy without losing some of their energy (for example, in an electric motor an electric current heats the wires, which is wasted energy. In all machines a great deal of energy is lost by being converted to a form of heat.
A mechanical energy can be converted entirely into heat, but heat cannot be converted into mechanical energy, i.e., work, without losing some of it.) The mathematical expression that shows the decrease of the energy in numbers is called anthropy (entropy N.) (Each event increases anthropy by one number by decreasing energy). One of the best examples of the reversal phenomenon is the clock. The mainspring is dried and compressed, then this compression is reversed and the mainspring starts to open and turn into mechanical work. But even in this there is a loss of energy, the mechanical work of the mainspring is less than the energy of compression.
