REVERSIBLE AND IRREVERSIBLE PROCESSES

Reversible Process

A thermodynamic process is reversible if the process can be turned back  to their original states, with no other change anywhere else in the universe

Question 1

No spontaneous processes of nature are reversible

Effect of Dissipating Forces

No process can be reversible, since heat energy is not entirely converting into work (η =1)

Since dissipative effects are present everywhere and can be minimised but not fully eliminated. This is one of the reason that most processes  are

Irreversible Process

Question

An irreversible process is a process that cannot return both the system and the surroundings to their original conditions. Select the following which consistent with irreversible process.

Answers

All most all process are irreversible in nature

Quasi-static processes are irreversible

Irreversible processes are consistent with Second Law of Thermodynamics

Dissipative factors in a process make it as irreversible
