Aseertion: Thermodynamics process in nature are irreversible.
Reason: Dissipactive effects cannot be eliminated.

Assertion: Thermodynamics process in nature are irreversible. Reason: Dissipative effects cannot be eliminated.

(A): Thermodynamics process in nature are irreversible. (R ): Dissipative effects can not be eliminated.

A : In nature all thermodynamic processes are irreversible. R : During a thermodynamic process it is not possible to eliminate dissipative effects.

Why are spontaneous/natural processes irreversible?

Assertion : All spontaneous processes are thermodynamically irreversible. Reason : In a reversible isothermal process, there is no net change in entropy.
