Sweta don't be confused with linga Reddy. Entropy do remain constant but not volume. See these two formula.

For reversible Adibatic expansion increase in entropy due to volume is compensated by decrease in temperature hence entropy remain constant.

The adiabatic process i.e. the entropy of a system remains constant. In other words, a reversible adiabatic process is an isentropic process at the same time. In this irreversible...

Every thing will be zero if volume is constant. See the formula
check it

Sweta so Adibatic process cannot occur with constant volume.
• Suman Kumar
Never adiabatic can't occur at constant volume. Remember in reversible adiabatic problem PV gamma = constant. For adiabatic process du = dw du = Cvdt There will be change in the ...

Now, since the process is adiabatic, so the heat transfer is zero and so the entropy change is zero through heat transfer. And if the process is also reversible, then there is no ...

Entropy remains constant in an adiabatic process which is also reversible. For the sake of simplicity consider the case of closed system, i.e. a control mass, which does not excha...

adiabatic process is a thermodynamic process during which no energy is transferred as heat across the boundaries of the system. As there is no exchange of heat with surroundings, s...
