Is melting reversible or irreversible?

Melting is a reversible change. If a block of chocolate melts, it can be frozen again to make an identical block of chocolate. Other changes are permanent: It is impossible to get back to the starting point.

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.) Thereof, 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.

Correspondingly, what is the basic difference between reversible and irreversible process?

The basic difference between reversible and irreversible processes is that in the reversible process the system remains in thermodynamic equilibrium, while in the irreversible process the system does not remain in thermodynamic equilibrium. What is reversible change give two examples Class 6? Answer: Reversible changes are those changes that can be reversed. Example: Melting of ice and freezing of water.

Accordingly, is jelly reversible or irreversible?

Well, what about setting jelly? Irreversible. Why? Because if you make jelly and it sets you can't get back to the solid lumps in the packet. Can all changes always be reversed? Nope...... only physical changes can be reversed,chemical changes are irreversible..

Why burning of paper is an irreversible change?

The burning of paper is an irreversible change. During burning of paper, the paper burns to produce ash and smoke. This ash and smoke cannot be converted back to the original paper so, its a change which cannot be reversed. Hence, its an irreversible change.
