“If a process can be carried out in such a way that the effect produced by it on the system as well
“Any change which causes the thermodynamic variables of a system to have a new set of values is called a thermodynamic process.”
Whenever work is done by the surroundings or by some external agency or vice versa, a process is said to be occurring.
2 .What do you mean by reversible & irreversible processes ?
as system can be completely restored to their initial states and no changes are left in any of the system taking part in process or in the surroundings,then the process is said to be reversible process.”
If a process does not satisfy these conditions, it is called irreversible.
Thus “the processes which produces a permanent change in the thermodynamic state of the system and cannot be retraced in the opposite order are known as irreversible processes.”
