What is reversible and irreversible process?
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
Is dissolving salt in water reversible or irreversible?
This is a reversible process.
Is an isothermal process necessarily internally reversible?
No, an isothermal process is not necessarily internally reversible.
Is evaporation a reversible or irreversible separation?
Evaporation is a reversible process.
How come world thermodynamicists fail to recognize that what makes coal combustion the energy of choice for electricity is the reversible piston turbine reversible process?
I am not sure what you mean. What process is that? Any combustible fuel will work, not just coal. You can read about the thermodynamics part by looking for a description of the "Carnot engine". The process is NOT reversible; although the Carnot engine is reversible in theory, there are always losses in practice that make it irreversible; also, the fact of burning the coal is not reversible.
Is a Bunsen burner on reversible or irreversible?
A Bunsen burner is an object: it is not a process of any kind.
Is evaporation reversible change?
Yes it is reversible and the process is called condensation!
What is the difference between reversible and cyclic process?
A reversible process is one that can be undone with no change in entropy of the system and surroundings. A cyclic process is one that starts and ends at the same state, with the system going through a series of state changes. All reversible processes are cyclic, but not all cyclic processes are reversible.
Does the entropy of the universe increase when a system undergoes a reversible process?
Yes, the entropy of the universe increases when a system undergoes a reversible process.
What is a reversible process?
A reversible process is one in which entropy doesn't increase. In other words, it should be possible to go through the process, and then to reverse the process (go through the process in reverse order), without using any energy.Note that this is an idealization; in general, REAL processes may approach a reversible process, but usually they won't be 100% reversible - some energy is wasted when going "back and forth".
Is density reversible?
Density is a property not a process.
Are there any process that are reversible?
Yes, lots.
