entropy of system for a reversible adiabatic process is equal to zero.
entropy of system for a irreversible adiabatic process (like free expansion) can be achieved by the following formula:
Delta S= n Cp ln(V2/V1) + n Cv ln (P2/P1)
Adiabatic mixing of two fluids is irreversible because it involves an increase in entropy. When the two fluids mix, their individual molecular arrangements are disrupted, leading to increased disorder and randomness in the system, which is reflected in higher entropy. This irreversible increase in entropy makes the process of adiabatic mixing irreversible.
"Adiabatic process" refers to processes that take place in a closed system with no heat interaction with it's surroundings. "Isentropic process" refers to processes that take place in a closed system with no heat interaction with the surroundings (adiabatic process) and internally reversible. This is, no internal generation of entropy, entropy stays constant, which is what is meant by "isentropic". We can also say, an isentropic process is one where entropy stays constant, and no heat interaction of the system with the surroundings takes place (adiabatic process). Or, an adiabatic process can be irreversible, or reversible (isentropic).
Yes. Diffusion will increase the entropy.
The entropy of the universe is increasing
A process where entropy remains the same is an isentropic process. In an isentropic process, there is no net change in the entropy of the system. This typically occurs when there is no heat transfer and the system is adiabatic and reversible.
In an adiabatic process, entropy remains constant.

During adiabatic expansion, entropy remains constant. This means that as a gas expands without gaining or losing heat, its entropy does not change.

No, a reversible adiabatic system is also known as isentropic.
Yes. Diffusion will increase the entropy.
General compression techniques look for repeated patterns which can be compressed to a single iteration of the pattern. A data stream with high entropy will have relatively few repeated patterns, and will decrease the compression ratio.
A perfectly ordered crystal at absolute zero is not apt to increase entropy, as entropy tends to increase with higher temperatures and disorder.

An adiabatic process is a thermodynamic process, there is no gain or loss of heat.
Yes, the hydrophobic effect contributes to an increase in entropy.
