WebMar 9, 2024 · Solution 2. Irreversible free expansion of a gas in adiabatic condition is not isentropic. There is an increase of entropy. The equation of dS=dQ/T is not an accurate equation, the actual equation should be dS=dQ (reversible)/T. For dQ of irreversible the equation should be changed into the clausius inequality form which is dS> dQ … Webadiabatic process, in thermodynamics, change occurring within a system as a result of transfer of energy to or from the system in the form of work only; i.e., no heat is …
The mathematical equation for an ideal gas undergoing a reversible (i.e., no entropy generation) adiabatic process can be represented by the polytropic process equation where P is pressure, V is volume, and γ is the adiabatic index or heat capacity ratio defined as WebEntropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work. The more disordered a system and higher the entropy, the less of a system's energy is available to do work. Although all forms of energy can be used to do work, it is not possible to use the entire available energy for work.
WebJan 5, 2009 · 4. There are two compartments, each has half volume of the total volume, separated by an insulating partition. The whole setup is adiabatic. n mole of a monatomic gas with temperature T1 and pressure P in the left while in the right m mole of monatomic gas with termparture T2 and pressure P there. Now remove the partition so two gas mix, … WebSep 9, 2024 · wrev = − PΔV < 0. According to Equation 13.4.15, this means that qrev must increase during expansion; that is, the gas must absorb heat from the surroundings during expansion, and the surroundings must give up that same amount of heat. The entropy change of the system is therefore. ΔSsys = + qrev T.
