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 reversed change? A change which can happen backward, that is, can be reversed is called a reversible change. If you keep water in the freezer for some time, it transforms into ice. But as soon as you take it out of the freezer, it turns into water again. This is a reversible change.

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. Is melting chocolate reversible or irreversible? Melting chocolate is an irreversible change. Heating materials always causes reversible changes. An irreversible change is one that cannot be changed - back.

Then, is rusting reversible or irreversible?

After viewing, ask: "Is rusting a reversible or an irreversible change?" (It is irreversible - the damaged metal cannot be returned to its former state.) Is ice reversible or irreversible? when ice is heated the ice melts away and change its state. again if the ice is cooled it come back into ice state. so, ice is melting and turning back into ice again.it is a reversible process.
