Question

Assertion : An adiabatic process is an isoentropic process.
Reason : Change in entropy is zero in case of adiabatic process.

✓

Answer

(a) Change in entropy, $\Delta S=\frac{\Delta Q}{T}$. In an adiabatic change, heat transfer $\Delta Q=0 . \therefore \Delta S=0$, or $S=$ constant i.e., entropy remains constant in an adiabatic process, or an adiabatic process is an isoentropic process.

Assertion : Newton's rings are formed in the reflected system. When the space between the lens and the glass plate is filled with a liquid of refractive index greater than that of glass, the central spot of the pattern is dark.
Reason : The reflection is Newton's ring cases will be from a denser to a rarer medium and the two interfering rays are reflected under similar conditions.
