Right Answer is: B

SOLUTION

Explanation:

Quasi-static process

  • A quasi-static process is a process in which the state variables of a thermodynamical system change infinitely slowly, thus the system appears nearly static.
  • It is a hypothetical and ideal process which is reversible and experiences thermodynamic equilibrium at every stage of the process.
  • A quasi-static process can be assumed to be a Reversible process.

Following points are important regarding Reversible and Irreversible process.

Reversible Processes

  • A thermodynamic process driving from initial state to final state is said to be reversible, if the system as well as its surrounding returns back to its initial state, without any change in the universe.
  • The processes which can be idealized as reversible are Motion without friction, Expansion/ compression with infinitesimal pressure difference, Energy transfer as heat with infinitesimal temperature difference.

Irreversible Processes

  • A thermodynamic process that does not return back to its initial state is termed as an irreversible process. 
  • The examples of irreversible processes are Motion with friction, free expansion, Expansion/ compression with finite pressure difference, Energy transfer as heat with finite, mixing of matter at different states, Mixing of non-identical gases.
