## Main Question or Discussion Point

Isentropic means a process where entropy remains constant. Now formula for entropy is

ΔS = ΔQ/T

now in an isentropic process, ΔS=0......so that means ΔQ = 0 ....right???

but if ΔQ = 0, that is an adiabatic process.

so are isentropic and adiabatic processes are same thing??

thanks.
