An irreversible process occurs whenever there is an increase in entropy. Entropy can be thought of as a measure of "wasted" energy, that is, energy that cannot be converted to useful work. Therefore any process which results in an increase in entropy wastes some portion of energy that cannot be recovered, and so the process is irreversible.
A Bunsen burner is an object: it is not a process of any kind.
Iron sulfide is a chemical compound. A process or reaction may be reversible or irreversible; a compound isn't.
Irreversible
No. It's a chemical change because the process is irreversible, there is a change in colour and a change in odour.
Cell differentiation
Rusting is an irreversible process.
A finger can go without circulation for about 6-8 hours before irreversible damage occurs.
Very simple The Reversible Process: That type of process that work cycle, it mean to complete revolution and come back to the initial point from where it start. Example are Carnot Cycle. Two and Four stroke engine. Irreversible Process: Opposite to reversible process called irreversible process. Example are Electricity
Corrosion is typically considered an irreversible cell reaction. It involves the degradation or deterioration of a material due to chemical or electrochemical reactions with its surroundings, leading to a loss of material and structural integrity. Once corrosion occurs, it is difficult to reverse the process completely.
Portland cement (and the concrete, mortar, thin set, or other masonry product made from it) doesn't dry. Rather, it cures by a chemical reaction initiated by putting water in it. The reaction is irreversible; hence, adding water to cement is an irreversible change.
Irreversible means unable to be undone or reversed. If something has done "irreversible damage", it means that the damage will not heal.
Evaporation is a reversible process.
A Bunsen burner is an object: it is not a process of any kind.
Iron sulfide is a chemical compound. A process or reaction may be reversible or irreversible; a compound isn't.
This is a reversible process.
Spontaneous processes are irreversible because they involve an increase in entropy, or disorder, in the system. This increase in entropy leads to a loss of energy that cannot be fully recovered, making the process irreversible.
Burning is an irreversible change.
