Which of the following processes is an iso-entropic process?

Question

Which of the following processes is an iso-entropic process?

Options:

A . Isothermal process

B . Adiabatic process

C . Isobaric process

D . Isochoric process

Answer: Option B
:
B
What do you mean by iso-entropic process?

\Rightarrow

The name itself is giving you the answer.
The entropy should be same before and after the process occurs.
Here we know that,

Δ S = \frac{d q}{T}

In case of adiabatic process,
dq = 0
Therefore

Δ S

= 0
