Question

what is reversible and Irreversible process in Thermodynamics

Answer 1

In thermodynamics, a reversible process is a process whose direction can be "reversed" by inducing infinitesimal changes to some property of the system via its surroundings, with no increase in entropy. Throughout the entire reversible process, the system is in thermodynamic equilibrium with its surroundings.

Answer 2

According to science, there is no thing in the universe that can be reversed(very few exceptions). But according to thermodynamics, reversible process are assumed...

Reversible Process - It is a type of process in which the changes take place infinitely small.

Irreversible Process - Well you know it....
