Question

what is reversible and irreversible process
​

Answer 1

Answer:

Changes that can be reversed ar e called reversible change.

changes that cannot be reversed are called irreversible change

Answer 2

Reversible process :

$\bigstar$ It take place in infinite number of infinitesimally small step and it would take infinite time to occur.

$\bigstar$ It is imaginary as it assumes the presence of frictionless and weightless piston.

$\bigstar$ It is in the state of Equilibrium at all the stage of operation.

$\bigstar$ Workdone by a reversible process is greater than the corresponding irreversible process.

Irreversible process :

$\bigstar$ It take place in a single step.

$\bigstar$ It is real and can be performed.

$\bigstar$ It is in equilibrium state only at the initial and final stage of the operation.

$\bigstar$ Workdone in irreversible process is smaller than the corresponding reversible process.
