Isothermal means the heat is constant throughout how come it is isentropic?

dq/t = 0 the cycle is reversible.
dq/t<0 the cycle is irreversible and possible.
dq/t>0 the cycle is impossible.
Entropy = dq/t.
dq/t<0 the cycle is irreversible and possible.
dq/t>0 the cycle is impossible.
Entropy = dq/t.

I think isentropic means entropy is constant it means that temperature is also constant and for thermal equilibrium temp. And pressure both are constant so the answer is isentropic.

Isentropic const means constant entropy but it does not mean its const pressure so how it's possible?

If two body are in thermal equilibrium then the heat does not flow so the answer Is isentropic.

Isentropic because in an ideal condition, there is no heat transfer between system and surroundings, therfore flow inside the system be isolated from the heat transfer from the surroundings, then the flow of steam is isentropic.

Yes, isentropic.
Because isolated condition apply.
Because isolated condition apply.

Thermal equilibrium means there is no change in temperature of a system so if there is no change in temperature that means the temperature is constant so the answer will be isothermal (C=T).

I think Hyperbolic will be the answer.

I think if thermal equilibrium dt=0 so isentropic process heat is zero Q=0 so it is isentropic
