A process is said to be irreversible when it doesn't come back to its original state. So their must be some energy losses and heat is also a form of energy.

In irreversible process some losses will takes places for example man walk in forward direction is easy but in reverse direction little difficult.

All above are wrong. Actually in irreversible process available energy decreased which makes the system to lose energy in form of heat.

Cyclic process are also irreversible in nature and in cyclic process there is no loss of heat energy due to the first law.

Irreversible process or natural process is open to atmosphere. The process can't reach final position. Example: the sun.

In an irreversible process, finite changes are made; therefore the system is not at equilibrium throughout the process.

Reversible process are cv, cp, ct process.

Irreversible process are throttling process and free expansion process.

I = Tods-dq.

Irreversible process does not go to completion, so that there is a loss in this process.

Irreversibility is occurs due to Heat transfer through a finite temperature difference in a process.

In irreversible process, there is a loss of heat due to friction, radiation, or conduction.
