If we adiabatically mix two liquid then perfect gas law is not necessary. But entropy change in the universe must be calculated by Second law of thermodynamics. Final entropy of then system is also a property. That so why we need second law.

Which one of the following sets of thermodynamic laws/relations is dir...
Introduction:
During an adiabatic mixing process, two streams of different fluids are combined without any heat transfer to or from the surroundings. This results in changes in the final properties of the mixture. To determine these final properties, certain thermodynamic laws and relations are involved. Among the given options, the correct set of laws/relations involved in determining the final properties during an adiabatic mixing process is option 'A', which includes the first and second laws of thermodynamics.
The First Law of Thermodynamics:
The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed but can only change its form. It is expressed as:
ΔE = Q - W
Where ΔE is the change in internal energy of the system, Q is the heat transfer to the system, and W is the work done by the system. In an adiabatic mixing process, there is no heat transfer (Q=0), so the first law simplifies to:
ΔE = -W
This equation helps in determining the change in internal energy of the system during the mixing process.
The Second Law of Thermodynamics:
The second law of thermodynamics deals with the direction and efficiency of energy transfer. It states that heat cannot spontaneously flow from a colder body to a hotter body without external work being performed. In the context of adiabatic mixing, the second law is involved in determining the direction of energy transfer and the resulting changes in entropy.
Explanation of Option 'A':
The first and second laws of thermodynamics are directly involved in determining the final properties during an adiabatic mixing process. The first law helps in calculating the change in internal energy of the system, while the second law determines the direction of energy transfer and the resulting changes in entropy.
