Reversible and Adiabatic Expansion of an Ideal Gas
Reversible and adiabatic expansion of an ideal gas is a process in which the gas expands without any heat transfer and does not encounter any frictional losses. This process is also called isentropic expansion.
The CORRECT expression for this process is S = 0.
Explanation:
S = 0 means that the entropy change is zero. In other words, there is no change in the disorder or randomness of the system. This is because the process is reversible, meaning that the gas can be compressed back to its original state without any loss of energy. Additionally, the process is adiabatic, meaning that there is no heat transfer between the system and its surroundings. Therefore, there is no change in the internal energy or enthalpy of the system.
U = 0 would imply that there is no change in the internal energy of the system, but this is not necessarily true for an adiabatic process.
H = 0 would imply that there is no change in the enthalpy of the system, but this is not necessarily true for an adiabatic process.
G = 0 would imply that the process is at constant temperature and pressure, which is not necessarily true for an adiabatic process.
Therefore, the CORRECT expression for reversible and adiabatic expansion of an ideal gas is S = 0.

For adiabatic condition
∆Q=0
∆Q=∆E+∆W
∆E=-∆W
∆S= ∆Q/T
∆S=0/T=0 (your answer)
∆G= ∆H-T∆S = ∆H-0 = ∆H
∆Q=0
∆Q=∆E+∆W
∆E=-∆W
∆S= ∆Q/T
∆S=0/T=0 (your answer)
∆G= ∆H-T∆S = ∆H-0 = ∆H
