What is meant by irreversible process?

Irreversible processes are actual processes carried out in finite time with real substances. In irreversible processes, heat transfer occurs through a finite temperature difference. ? In irreversible processes, mass transfer occurs through a finite chemical potential difference.

You can also ask why is entropy irreversible?

An irreversible process increases the entropy. This is because entropy is a state function, the change in entropy of the system is the same, whether the process is reversible or irreversible. Energy always flows downhill, which causes entropy to increase. Subsequently, why is reversible work more than irreversible? The reason why more work is done by the system in a reversible process than an irreversible process is entropy is generated within the gas in an irreversible process. Whenever entropy is generated within the system there is a lost opportunity for the system to perform useful work.

Is reversible work greater than irreversible work?

Reversible versus irreversible expansion of an ideal gas. Therefore, the work done on the gas is less in the reversible case than it is in the irreversible case. (Both work terms are less than zero. The absolute value of the reversible work is greater than the absolute value of the irreversible work.) What is an example of reversible? Reversible changes are changes that can be undone or reversed. Melting, freezing, boiling, evaporating, condensing, dissolving and also, changing the shape of a substance are examples of reversible changes.

Is water reversible or irreversible?

Reversible Change. Water in its solid state is called ice. When ice is heated, it melts and becomes liquid water. Further heating causes the liquid to change to a gas, called water vapor. When water vapor is cooled, it changes back to liquid water.
