The work done in the given process on the right part and the final temperature needs to be determined. Concept Introduction: In thermodynamics , a reversible process can be defined as the process which can be reversed to its original state. Hence, in reversible processes, both the system and surroundings are returned to their initial states. In general, all reversible processes are ideal processes and cannot occur naturally. On the contrary, an irreversible process cannot come back to its initial condition. All spontaneous processes in nature are irreversible processes. In an adiabatic process, the heat change is zero therefore the work done will be equal to the change in the internal energy.

(a)

Interpretation Introduction

Interpretation:The work done in the given process on the right part and the final temperature needs to be determined.

Concept Introduction: In thermodynamics, a reversible process can be defined as the process which can be reversed to its original state.

Hence, in reversible processes, both the system and surroundings are returned to their initial states. In general, all reversible processes are ideal processes and cannot occur naturally.

On the contrary, an irreversible process cannot come back to its initial condition. All spontaneous processes in nature are irreversible processes.

In an adiabatic process, the heat change is zero therefore the work done will be equal to the change in the internal energy.

(b)

Interpretation Introduction

Interpretation:For the given process, the final temperature in the left part and heat flowed into it needs to be determined.
