A process is reversible if it can be reversed without any loss of energy or increase in entropy. One way to determine if a process is reversible is to see if it can be undone by making small changes to the system. If the process cannot be undone without some loss of energy or increase in entropy, then it is irreversible.

Is the first law of thermodynamics applicable to irreversible process also.. Explain?
yes since it is law of energy balance so irrespective of the process it can be applied to any process but small change comes when we deal with reversible and irreversible processes. it can be explained in text form : please give attention to the text; CHANGE IN TOTAL ENERGY( it is sum of change in macroscopic kinetic energy and change in macroscopic potential energy and change in internal energy,U) = HEAT TAKEN BY THE SYSTEM {actually heat taken by the medium which we use often an ideal gas}(sum of heat given to the system from outside+ heat generated with in the system ) + WORK DONE BY THE MEDIUM OR SYSTEM {again it includes all kind of works such as expansion work shaft work electrical work etc. also when the process is IRREVERSIBLE it includes internal work which is consumed to overcome the friction} for reversible processes there is no dissipation of internal heat and internal work in that case we consider that the piston cylinder which we use to explain first law is frictionless . and also since they have a characteristic property of INFINITE SLOWNESS the reversible process can be considered at equilibrium at each state. For irreversible processes the heat is generally generates with in the system because we do not use the friction less piston cylinder arrangement.
Is breaking a window reversible?
Yes, breaking a window is reversible by replacing the glass with a new one. The process involves removing the broken glass shards, fitting a new pane of glass, and securing it in place.
How can one determine if a process is spontaneous?
A process is spontaneous if it occurs without any external influence or assistance. One way to determine if a process is spontaneous is by calculating the change in Gibbs free energy (G). If G is negative, the process is spontaneous.
What is difference between reversible machine and self locking machine?
A reversible machine can operate in both directions, allowing for bidirectional movement, while a self-locking machine locks in place once power is removed, preventing unintentional movement. Reversible machines like electric motors can change the direction of rotation, whereas self-locking machines like a screw jack maintain their position without external forces.
How can one determine the process of heat transfer in a given system?
To determine the process of heat transfer in a system, one can analyze the temperature changes and energy flow within the system. This can be done by measuring the initial and final temperatures of the system, calculating the heat input or output, and considering factors such as conduction, convection, and radiation. By understanding these factors, one can determine how heat is being transferred within the system.
What is the antonym of reversible?
irreversible, non-reversible, one-sided
What is the difference between reversible and irreversible communication?
The difference between reversible and irreversible is that reversible changes can be changed and irreversible changes cannot. Apart from sometimes but it usually is really hard. Also when the change is reversible no new substances are formed. When the changes are irreversible they are. Something that is reversible can be changed, something that is irreversible cannot be changed. For example, bread into toast is an irreversible reaction, because you cannot turn the toast back into bread.
Distinguish between reversible and irreversible electrochemical cell?
irreversible cells are those which require replacement of chemicals.when they give out electricity. these cannot be recharged. examples are : 1 =dry cell 2=zinc acid copper cell reversible cells are those in which reversible reactions are involved.these cells can brought back to their initial state by applying external potential difference
What do irreversible mean?
Irreversible means something that cannot be undone or changed. In physics, it refers to a process that cannot be reversed to return to the original state.
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.
What is the meaning of reversible and irreversible in cooking?
Reversible changes mean that i.e. if you make a chocolate sweet/lolly pop etc.. you can melt it back and make another one. Irreversible changes mean that i.e. if you crack an egg and it burns, you can not turn back into a raw egg in an unbroken shell again.
What is the definition of an irreversible reaction and how does it differ from a reversible reaction?
An irreversible reaction is a chemical reaction that proceeds in one direction only, meaning it cannot be easily reversed. In contrast, a reversible reaction is a chemical reaction that can proceed in both forward and reverse directions, reaching a state of equilibrium where the rates of the forward and reverse reactions are equal.
Is the decomposition reaction of calcium carbonate in an open container reversible or irreversible?
The decomposition of calcium carbonate in an open container is irreversible, because one of the decomposition products, carbon dioxide, is a gas, and since the container is open, this gas will mix with the natural atmosphere and never develop sufficient local partial pressure to reverse the reaction.
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 germination of seed reversible or irreversible?
lol
Is salty water reversible or irreversible?
... no?If your real question is "can you separate salt from water after you've mixed the two" ... sure. One simple way is to evaporate the water, leaving the salt behind.
What is the difference between a chemical change and a physical one?
chemical change is reversible whereas physical is irreversible e.g a paper after getting burnt cant be converted to paper again this is a physical change
